Abstract:W—Ni—Fe alloy coating and hard chromium coating were prepared on surface of27SiMn rod
and hardness theof two coatingswere then the wearresistance of
the two coatings were tested with aandfriction wear testingresults showedthatun—
der the same circumstance and testconditions,hardness ofthe W—Ni—Fe alloy coating afterheattreatment
was equivalent to that of hard chromium coating,and the wear resistance of the heat treated W—Ni-Fe
alloy alloy coatingwas superior thattoofhard chromium coating within acertain load range.
