八月 精抛光后 CoCrMo 铸造合金的枝晶结构。
CrCoMo alloys are distinguished by their excellent corrosion resistance, high strength, and outstanding biocompatibility. These properties make them preferred materials in medical technology, particularly for the fabrication of implants such as artificial hip and knee joints as well as dental prostheses. The alloys exhibit exceptional wear resistance and reliably maintain their mechanical properties even under high load and in contact with bodily fluids.
The addition of molybdenum further enhances corrosion resistance, while chromium promotes the formation of a stable, protective oxide layer on the surface. In addition to their use in the medical field, CrCoMo alloys are also applied in the aerospace and chemical industries, where the highest demands are placed on material durability.
A central aspect of quality assurance for CrCoMo alloys is metallographic examination. This includes microstructural analyses using light microscopy and scanning electron microscopy as well as the inspection for porosity, shrinkage cavities, and inclusions. In our “Preparation of the Month,” you will gain comprehensive insight into the complete preparation process for a CrCoMo alloy. Here, the Contero H fine grinding disc plays a decisive role: it is used between coarse grinding with a diamond disc and the polishing step, ensuring optimal preparation results. For this reason, we have selected the Contero H fine grinding disc as our Product of the Month.
