The wear of metals by relatively soft abrasives

摘要: Abstract In previous work, values were established for the relative wear resistance β of a range metals and alloys on hard abrasive, maximum hardness Hu surface material when strained plastically. The these materials is now considered abrasives moderate hardness, Ha, such as flint glass, with object explaining their characteristics under abrasion in soil. It found that b increases, compared value applicable to exceeds about 0.8 Ha. A secondary increase occurs H bulk concluded from this other evidence both reach only locally. Significant relationships between b/β Hu/Ha or H/Ha, show wearing action similar modified by damage abrasive grit. Scratching cease some conditions yield stress slightly abrasive. increases are much larger fine than coarse grit This associated plastic flow shattering For heterogeneous effect augmented due particles becoming more effective they large scale cutting. compares well results field soils. similarity types arising industrial practice classed scratching grinding noted.
