... that produce harder surfaces are nitriding, boronizing (boriding), and chromizing. The hardest metal coating is chromium plate, although hardened electroless nickel plate can attain values just under that of chromium. The surfaces that exceed the hardness of chromium are the cermets or ceramics, or surfaces...

... temperatures, techniques to produce alloy carbonitride layers have been developed ( Ref 54 ). Such coatings are produced on hardened and nitrided steels in vanadium- or chromium-containing chloride baths at temperatures between 550 and 600 °C (1020 and 1110 °F). The nitrided surface contributes nitrogen...

.... Steels containing aluminum, chromium, vanadium, tungsten, and molybdenum are suitable for nitriding because they readily form nitrides that are stable at the nitriding temperatures. For example, aluminum forms very fine AlN precipitates. Molybdenum, in addition to its contribution as a nitride former...
