To clarify the effect of Titanium Nitride (TIN) coatings on thefailure resistance and frictional characteristic and compare thiseffect with that produced by the heat treated coatings, two rollertests have been made and the stress resulting from the combinationof the Hertzian stress field and frictional force field on andbelow zhe contacting surface as well as the flash temperature risewere calculated. The failure resistance of the TiN-coated rollerpair was greater than that of the heat treated roller pair. Themechanism of failure resistance can be explained by the shearingstress (Hertzian stress + frictional force) acting on the contactsurface. This stress modifies the structure in the vicinity belowthe TiN layer which is then sheared in the wear trackdirection.
