wear resistance and wear conditions-wear resistant steel plate

Wear resistant material is not everything, the key to work is the reasonable choice of materials. The first thing is to give proper analysis on the working conditions and its wear mechanism, and learn well about the performance of wear resistant materials, and then take economy, reliability into consideration, choose the most appropriate wear-resistant materials to achieve the purpose of energy saving.

In abrasive wear cases, there is a relationship between wear resistant material hardness and abrasive hardness, hardness ratio Ha/Hm of wear resistant material and materials has a great influence on the wear rate. The results of many experiments found that K3=Ha/Hm=1.3-1.7，K2=0.7-1.1, the wear resistance of the work-piece can be significantly improved when we try to increase the hardness of metal materials and keep material hardness unchanged at the same time.

Material particle morphology, size and hardness can influence the wear resistance performance of materials, wear resistance. The micro hardness of various minerals : cement clinker 450-650, blast furnace slag 450-700, feldspar 650-700, bituminous coal 30-40, plaster 60-100, calcite 95-150, coal gangue 220-330, dolomite 250-350, limestone 250-400, steel-making slag 380-600, architectural glass500-600.

Wear resistance of material is not its inherent ability, wear rate of materials is different according to different wear conditions, also wear properties of materials change with wear conditions, each kind of materials require different wear resistance performance, which should have other requirements corresponding to hardness, toughness, strength, plasticity.
