Description
Technical field
The utility model relates to a kind of ceramic composite, specifically is meant a kind of metal ceramic composite wear-resistant material that is used for material-transporting system.
Background technology
In the material-transporting system of industries such as metallurgy, electric power, building materials, machinery, chemical industry, adopt high mangaenese steel and wear resistant alloy etc. to make abrasion-proof backing block mostly.Though the liner plate that metallic substance is made has good obdurability, this liner plate weight is big, and hardness is low; wear resisting property is poor, and the life-span is short, needs diligent rebush plate; this has increased the weight of working strength of workers undoubtedly, has increased cost, shuts down maintenance and has also reduced usage ratio of equipment.Therefore, the development of new high-abrasive material, the abrasion resistance of raising material-transporting system is the industrial circle question of common concern.Make abrasion-proof backing block casting commonly used or technique for overlaying with metallic substance at present, technique for overlaying is to make the complex abrasion-proof steel plate with high-abrasive material is deposited to substrates such as soft steel, as the paper " adding the application of powder bead-welding technology and hardfacing clad steel plate " of " welding technique " magazine publication in 1996, introduced a kind of technology of preparing of complex abrasion-proof steel plate.
The high strength that stupalith had, high rigidity, performance such as high temperature resistant, wear-resisting, corrosion-resistant, anti-oxidant are far superior to metallic substance and macromolecular material.But fragility is a deadly defect of stupalith.Therefore, stupalith only is suitable for the little operating mode of shock load.As utility model patent ZL03207616.9 " welded type wear-resistant ceramic sheet ", its ceramic plate is made through high-temperature firing technology by aluminum oxide powder, be provided with 1-2 conical welding hole at the middle part of ceramic plate, adopt plug welding technology to be connected on the wear member, some are connected to form integral body.This patent has solved ceramic plate has been pasted on the abrading section, the problem that comes off easily in the use.The wearing piece toughness plasticity of making of metallic substance is good, can withstand shocks, but hardness is lower, and wear resistance is relatively poor.Though stupalith hardness height, wear resisting property is good, and poor toughness is frangible.If both are combined make matrix material, can give full play to both advantages separately, reach both wear-resisting, shock proof again purpose.As publication number is the utility model patent " a kind of metal ceramic wear-resisting composite material and preparation method " of CN101024556A, this patent is a matrix with the abrasion-resistant metal plate, on steel plate, punching, wear-resistant ceramic material is embedded in the steel plate hole, and the gap between pottery and the matrix is done caking agent with organic or inorganic glue and is filled.The complex method of this pottery and metal adopts adhesive technology, and bonding strength is low, is unsuitable for hot environment, and caking agent is aging easily, makes stupalith come off easily, causes wearing piece to lose efficacy.Harsh day by day along with the component of machine applying working condition, as wearing and tearing, burn into high temperature etc., to low-cost, easy to use, production efficiency is high, the demand of the high-abrasive material of excellent performance is also more urgent.
Summary of the invention
The purpose of this utility model is exactly that bonding strength at metal in the existing ceramic-metal composite and pottery is low, caking agent is easily aging, wear-resistant ceramic comes off, is unsuitable for problems such as worst hot case easily, a kind of make metal and firmly welding of pottery have been proposed, thereby improve composite-material abrasive, reduce use cost, satisfy the metal ceramic composite wear-resistant material of advantages such as production requirement.
For achieving the above object, the utility model adopts following technical scheme: a kind of metal ceramic composite wear-resistant material, and it comprises substrate, offers several blind holes on the described substrate, be provided with the wear-resistant ceramic piece that is complementary with blind hole in blind hole, wear-resistant ceramic piece and blind hole are welded to connect.Described substrate thickness is at 3-50mm, and blind hole depth is less than substrate thickness; Perhaps described substrate thickness is provided with several through holes at 3-50mm on substrate, be the base plate of 2-30mm in the welding of the one side of substrate with the same size of substrate, thickness, makes all through holes become blind hole; Substrate is a kind of in soft steel, medium carbon steel, high carbon steel, low alloy steel, stainless steel, the high temperature steel.
Preferred soft steel of described substrate or low alloy steel.
The cross section of described blind hole is circle or Polygons (as rectangle, trilateral, rhombus etc.) or other regular shapes, and area is not less than 4 square millimeters, and the minor increment between the adjacent blind hole edge is not less than 0.5mm.
