In this study carburizing and boronizing processes were applied to powder metallurgy steel specimens and the mechanical and tribological properties of the substrate and coatings were evaluated under various process conditions.&#10The specimens, made from industrial test pieces, were carburized in a powder pack for a duration of 2-5 hrs at 850-950 ˚C. Similar specimens were pack boronized for 4 ...

Aluminide coatings have been studied for many years because of their excellent corrosion resistance in oxidizing, sulfidizing and carburizing environments. One of the factors that inhibits their application is a lack of sufficient data about their potential benefits. In order to address this issue, model coatings are being fabricated using a chemical vapor deposition (CVD process on ferritic (F...

Recent advancements in high-density lubricants enable P/M steels to be processed to densities approaching 7.40 g/cm in a single compaction step using heated compaction tools via the AncorMax D process. This broadens the number of suitable applications for P/M steels, including high performance gears. However, in addition to high-density, the microstructural and mechanical property requirements ...
