2.2 Immersion corrosion test According to ASTM standard G31-2004, the specimens were immersed in NaCl solution at 25 °C for obtaining the corrosion rate and macro corrosion morphologies of WC–Co hardmetal and WC–Al 2 O 3 composite, respectively. The mass loss after immersion corrosion each … Zobacz więcej The corrosion resistance of materials used in corrosive environment is a very important technical index, which is usually studied by electrochemical method. Electrochemical … Zobacz więcej (1) WC–Al2O3 composites has higher corrosion resistance than WC–Co cemented carbide in NaCl solution, due to the lower icorr and more positive Ecorr for WC–Al2O3 composites. In addition, the corrosion current … Zobacz więcej WitrynaImmersion corrosion experiments are conceived mainly to determine the general corrosion rate. They are very flexible in terms of choice of solution, solid materials to be added (near- or far-field materials), or atmosphere, etc. Other experimental approaches to corrosion testing are also being applied.
