The Spatial Configuration Size Affects The Properties Of ZTAp/high Manganese Steel Matrix Composites

High manganese steel as a kind of historic wear-resistant material.Under the impact,The surface of the workpiece can quickly produce the working hardening effect.It has good abrasion resistance.Under actual working conditions,when the impact load is not high enough,it can not form sufficient working hardening effect on the workpiece surface.The wear resistance and service life of high manganese steel workpiece are affected.In order to further improve the wear res istance of high manganese steel,in this paper,a ceramic granule with different space configuration size is prepared to enhance the composite material of high manganese steel.The properties of the composites were studied.In this paper,the effects of prefabricated body,ceramic active micropowder and binder on the infiltration of composite materials were studied.In the precast of cellular space structure,its aperture/pore wall size is around 1.71,which is best for the infiltration of metal liquid,and the compound effect of composite material is the best.When the added amount of ceramic active micro powder is 2%,the infiltration effect of the composite material is the best.The addition of wa ter glass is between 3% and 5%,and its metal solution is the best for precast.The hardness and compression properties of composite materials with different space configurations were investigated.The hardness of the composite area with different spatial configuration size is greater than that of the high manganese steel matrix.When the hole wall size is certain,its hardness decreases first and then increases with the increase of its pore diameter,and its hardness is up to 46.88 HRC.Under certain conditions of aperture size,with the increase of the hole wall size,its hardness is increasing,and its rockwell hardness is up to 46.3HRC.In terms of compression performance of composite materials with different spatial configurations,when the ratio of aperture/hole wall is 1.5~2,the compression performance of composite materials is the best,and the bonding strength of the interface is the highest.However,the crack propagation of compression experiment is mainly influenced by the interaction of particle matrix.In this paper,the wear properties of three-body abrasives with different space configurations are studied.As the ratio of pore area/wear surface increases,the wear resistance of composite material decreases.When the ratio is about 0.28,the wearability of the composite material is the best,which is 1.6 times higher than that of the high manganese steel.In addition,composite materials with the same space configuration size were treated with heat treatment,and their wear resistance was 1.3 times.In this paper,the wear properties of impact abrasive wear of composite materials with different spatial configurations are studied.As the ratio of the size/change direction of the hole wall decreases continuously,its wear resistance is continuousl y reduced.When the ratio of the dimension of the hole wall/the dimension of the direction(L1/ L2)is 0.3,its wear resistance is the best,which is 1.37 times higher than that of its high manganese steel.In the same space configuration size composite materials were treated with heat treatment,and the wear resistance was 1.21 times.
