WEBFeb 1, 2019 · 2. Use a “non-galling”, or “galling-resistant” grade to replace one of the matting parts. 3. Change the hardness also: Give some thought to which of the parts (male or female) you wish to be sacrificial; i.e. which one can you most easily replace. Then, approach the difference in hardness accordingly.
WEBHardness–In general, resistance to wear is increased by increasing hardness, provided other factors remain constant. There is some question, however, whether the controlling hardness is the bulk hardness or simply surface hardness. It has been stated that to increase wear resistance, hardness should be increased by alloying or heat treatment.
