According to the ASTM, additive manufacturing is a process used to assemble materials from 3D models, usually layer by layer and in opposition to substractive manufacturing, such as machining and cutting.
Additive manufacturing allows to build parts with less loss of material while also limiting the number of production steps. Additive manufactured parts do not need to be machined from a bulk block, there is no riser to be removed and it is not necessary to shape multiple preforms to obtain the final product. Usually, a final machining is necessary to obtain the desired surface finish.
CMQ’s corrosion assessment includes various equipment to support companies through their product durability concerns. As per the company needs, our team will follow international testing standards or develop new and innovative testing methods to likely simulate the real-life environment in which the material or equipment will perform and to monitor corrosion processes in real time. This in order to help our industrial partners to reduce future risk or damages to their assets.
CMQ can develop a test for your needs. For example, intergranular corrosion refers to the material degradation for which the corrosive attack progress along the grain boundaries of a metal after exposure to a corrosive environment. We utilize different chemicals and test conditions to evaluate a range of metallic materials for intergranular corrosion (e.g ASTM A262, ASTM G110 and ASTM G67).
