ACE is a collection of 16 essential corrosion software applications for daily use by corrosion engineers, corrosion researchers, and corrosion technicians in laboratories and in fields. ACE can significantly increase the efficiency, productivity, consistency and accuracy of corrosion related calculations, conversions, CP survey data assessment, materials selection, and corrosion prediction. ACE helps you do more in less time with practically everything related to corrosion. If you cannot find the features you want in ACE, do let us know and we will add the features for you to ACE free-of-charge for licensed users.
Figure 1 below shows the screen shot of ACE. There are 16 modules under the respective Tabs in ACE.

Detailed Feature Description of Apps for Corrosion Engineers CRU: Corrosion Rate Unit Converter - Converting between All Corrosion Rate Units for All Metals and Alloys Corrosion rate units commonly reported in the corrosion literature include:
Converting the corrosion rate from one unit to another for comparison and for engineering applications is frequently required for numerous metals and alloys. For a given alloy, the conversion factors are different for each unit (µA/cm2, mpy, µm/y, mm/y, mdd, gmd); for a given unit conversion (e.g. mdd => mpy), the conversion factors are different for different alloys which are influenced by the density, chemical compositions, atomic mass of elements, and the valence of metallic elements in the alloy. Manual conversion requires multiple steps of calculation using a set of equations. The procedure is time-consuming and prone to errors, particularly for many engineering alloys that contain multiple metallic elements in their chemical compositions. Try to manually convert a corrosion current density of 1 µA/cm2 to mm/y for the titanium alloy Ti-3Al-8V-6Cr-4Mo-4Zr and see for yourself how long it takes you to get an accurate conversion.
ACE-CRU -Corrosion Rate Unit Converter is the only device and OS independent software tool on the market for instantly converting between all corrosion rate units for all metals and alloys with precision. Users simply choose the metal or alloy from the list and the conversion between all corrosion rate units for the selected alloy is instantly displayed (Figure 1). If a metal or alloy is not available in the database, users can easily define their own alloys for the conversion (Figure 2).
Figure 2 User-Defined Alloy in Corrosion Rate Units Converter
ACE-CRU Corrosion Rate Units Converter provides error-free conversion conforming to relevant ISO, ASTM and NACE standards. Current database in ACE-CRU Corrosion Rate Units Converter contains the following metals and alloys:
Aluminum and Aluminium Alloys Aluminum
AA1100 (A91100)
AA2060 (A92060)
AA7050 (A97050)
Copper and Copper Alloys

Stainless Steels and Alloys
Nickel and Nickel Alloys
200 (N02200)
Carbon Steels, Cast Irons and Low Alloy

Users can define their own alloy for the conversion by entering the chemical composition (wt%) of the metallic elements in the alloy. ACE-CRU Corrosion Rate Units Converter instantly displays the results of the conversion between all corrosion rate units, saving users' time and effort.
Application Example Weight loss coupon test for magnesium alloy AZ61 reported a corrosion rate of 1.123 mdd. What is the equivalent corrosion current density in uA/cm2? What is the corrosion rate expressed in um/y? What is the corrosion rate expressed in mpy? Answers to the above are instantly available (Figure 3) after selecting the alloy AZ61 from the dropdown list and entering the weight loss data "1.123" in the "mdd" field: The equivalent corrosion current density is 1.0472 uA/cm2. The corrosion rate in um/y is 22.7844. The corrosion rate in mpy is 0.897.

REF: Reference Electrode Potential Converter - Converting measured potentials at measurement temperatures to equivalent potentials at 25°C vs. reference electrodes commonly used in labs and in fields.
Figure 4 ACE-REF Reference Electrode Potential Converter with Temperature Correction Corrosion laboratories worldwide use a variety of reference electrodes for specific reasons. National and International cathodic protection standards use different reference electrodes for specifying cathodic protection criteria. Copper copper-sulphate electrode (CSE) is specified for cathodic protection of underground structures such as pipelines and storage tanks; silver-silver chloride electrode (SSC) is specified for cathodic protection of structures immersed in seawater; saturated calomel electrode (SCE) is most widely used in laboratories. Electrode potentials are sensitive to temperature. Potentials measured at temperatures other than 25°C have to be converted to equivalent values for cross-referencing and comparison. For example, Cathodic protection potential survey data are collect in the fields at seasonal temperatures (not the standard 25°C). It is essential that the CP system meets the protection criteria that is referenced to -0.85 V (CSE) at 25°C for a buried pipeline. The ACE-REF module instantly converts the measured potential at the measurement temperature to the equivalent potential at 25°C on commonly used reference electrode scale, or a user-defined reference electrode scale. Try to manually convert the potential of -0.850 V (CSE) measured at 45°C to the potential at 25°C on the SSC (SJ) scale and see how long it takes to get an accurate conversion. In ACE-REF, it take less than a second and the conversion is done for all common reference electrodes used in labs and in fields. In this example, the reading of -0.85 V (CSE) at 45°C does not meet the CP protection criteria as the equivalent potential at 25°C is -0.832 V (CSE), as shown in Figure 4 above. In contrast, a potential reading of -0.837 V CSE) at 10°C meets the cathodic protection criteria as the equivalent potential at 25°C is -0.850 V (CSE), as shown in Figure 5.
Figure 5 ACE-REF Reference Electrode Potential Converter for Cathodic Protection Applications ACE-REF can literally be a life-saver for cathodic protection contractors, cathodic protection technicians, cathodic protection technologists who are involved in meeting both the technical and the contractual requirements of cathodic protection criteria. Facility owners can use ACE-REF to instantly verify if the CP survey data meet the protection criteria at a specific location and in a specific season. Users of ACE-REF can easily define their own Reference Electrode scale for conversion. In Figures 4 and 5 above, the user-defined reference electrode named "User's Ref" has a standard potential of 0.288 V (SHE) at 25°C with a temperature coefficient of -0.433 mV/°C. |

In an electrolyte of pH7 at 25°C, O2 gas will be evolved on the electrode surface if the electrode potential (vs. SCE) is 0.650 V.

CP-Pol: Cathodic Polarization Assessment and Corrosion Rate Calculation
- Assessing the effect of CP polarization on the corrosion rate when CP is ON.
This software tool can be used to optimize cathodic protection design, to determine cathodic protection criteria, and to evaluate CP survey data.
Figure 7 CP-Pol: Assessing the effect of CP polarization on the corrosion rate when CP is ON. A user simply enters the temperature and cathodic polarization, CP-Pol calculates the corrosion rate reduction factor. If the native corrosion rate (no CP) is known (typically less than 0.25 mm/y in soil or seawater), the corrosion rate when CP is on is calculated. CP-Pol allows users to enter the Tafel slope value for use in the computation. |

DO: Dissolved Oxygen Calculator
This software tool helps you with the following tasks:
Figure 8 Calculation of Dissolved Oxygen in Waters at a Specified Temperature. Users have complete flexibility in defining the fluid by entering either the salinity, or conductivity, or TDS, or just select one of the waters without the need to have the water analysis results.
Figure 9 Calculation of Dissolved Oxygen and O2 Diffusion Limiting Current Density in Waters at a Specified Temperature. The solubility of oxygen in water is dependent on both temperature and salinity (salt concentration). The oxygen diffusion limiting current density and the corresponding corrosion rate in mm/y for carbon steels are predicted in this module. A user can use the CRU module to convert the diffusion limiting current density to the preferred corrosion rate unit for any metal or alloy. |
