TRACK AND/OR HINGE PIN HAVING IMPROVED ABRASION, CORROSION AND GALLING RESISTANCE

摘要

An abrasion, corrosion and galling resistant pin (10) comprises a cylindrical shape, an outer surface (50), a first end portion (20), a second end portion (30) and a middle portion (40). The pin (10) also comprises a first bearing surface (22) defining the first end portion (20) and a second bearing surface (32) defining the second end portion (30). An abrasion resistant coating (60) is deposited on at least one of the first bearing surface (22) and the second bearing surface (32). The coating (60) is selected from the group consisting of chromium nitrides, chromium carbonitrides, and mixtures thereof.
