Such standardized measurements can produce two quantities: abrasion rate and normalized abrasion rate (also called abrasion resistance index). The former is the amount of mass lost per 1000 cycles of abrasion. The latter is the ratio of former with the known abrasion rate for some..

Effect of Heat Treatment of Wild Cherry Wood on Abrasion .

ABSTRACT In its wise use, many properties of wood are important. Among these properties, wood abrasion resistance (AR) and withdal capacity of screws (WCS) are deemed to be relatively significant. It is well know that heat treatment changes the resistance features of wooden materials by changing the structural..
