摘要： A process is provided for boriding metals and metal alloys in a fluidized bed at a temperature of from about 580.degree. to about 1300.degree. C. As a boriding agent, there was used a granular material comprising essentially spherical particles having a particle size of from about 0.025 to about 5.00 mm, which granular material was manufactured by spray drying a preferably aqueous suspension or dispersion based on materials that yield boron, and which can contain fillers, extenders and binders.

摘要： The disclosure provides a method of manufacturing a cutting blade for an agricultural implement. The method includes forming the cutting blade to define a final shape having an exterior surface. The cutting blade is treated with a surface diffusion hardening process to form a surface hardened layer disposed over a core layer. The surface hardened layer is very thin, approximately 0.1 mm, and exhibits an apparent hardness equal to or greater than 1000 HV. After the surface diffusion hardening process, the cutting blade is treated with a through hardening process, such that the core layer exhibits a Rockwell Hardness C Scale value between the range of thirty five (35) and fifty five (55).

摘要： A chain element (2), in particular a chain pin (4), for joining at least two chain links (3), characterized in that it comprises a surface layer (5) containing boron and vanadium, formed by at least one step of diffusing boron and vanadium in the areas of the chain element (2) which are close to the surface. The surface layer (5) containing boron and vanadium is formed by boriding and subsequently vanadizing a substrate material having a carbon content of 0.60 wt.-% to 1.0 wt.-%.
