Abstract
The invention discloses an ion arc induced metal surface layer composite TiN reinforcing method with TiO2 and N2 gas as components, and relates to the technical field of metal surface reinforcement processing. The method comprises the following steps: applying TiO2 powder on a metal surface, and in N2 gas atmosphere, scanning with plasma arcs on the metal surface to which the TiO2 powder is applied. By adopting the above method, TiN can be generated on the metal surface layer in an in-situ composite manner, thus enhancing the metal surface and improving the wear resistance.
Description
Technical field
The present invention relates to metal surface enhanced treatment process technical field.
Background technology
Titanium nitride (TiN) is a kind of non-metering compound, has simultaneously the characteristics of Metallic Solids and covalent crystal, and fusing point is up to 2955 ℃.As top coat, TiN has the good comprehensive mechanical properties such as high rigidity, wear-resistant, high temperature resistant, anti-thermal shock, frictional coefficient be low, is one of thin-film material of studying at present and being most widely used.TiN successfully is applied to as coating be considered to the revolution on the metal cutting tool technograph on the instruments such as cutter, drill bit.
The technology of preparing of TiN coating mainly is physical vapor deposition (PVD) and chemical vapour deposition (CVD) at present.PVD method formation temperature is lower, coating is thinner, and is low with the bonding strength of matrix, and coating is easy to peel off from substrate, and relatively poor around plating property.CVD method depositing temperature is high, but has surpassed the thermal treatment temp of most Common Use Tools materials, thereby it is very limited to can be used to carry out the cutter material kind of coating; Secondly, CVD needs a cover to provide and prepares the equipment that contains the Ti halide gas take muriate as raw material, complex process, and cost is higher, and is inconsistent with the green industry of present promotion.
No matter be PVD method or CVD method, the TiN coating that obtains is all thinner, and thickness only has several micron (μ m), and coating is mechanical bond with matrix, and bonding surface intensity is low, and the use floating coat easily peels off.
Summary of the invention
Purpose of the present invention aims to provide a kind of structural carbon steel surface TiN intensifying technology, can make structural carbon steel upper layer original position composition generation TiN, thereby the structural carbon steel surface is strengthened and the raising wear resistance.
The present invention is achieved by the following technical solutions:
Apply with TiO in the metallic surface
2Powder is at N
2Under the atmosphere, use plasma arc at deposited TiO
2The metallic surface of powder is scanned.
Can at metal surface original position composition generation TiN, realize reinforcement and raising wear resistance to the metallic surface by above method.
The present invention has the following advantages:
1, TiN is at metal surface original position composition generation, rather than at surface deposition, does not therefore have the bonding force problem of coating and matrix;
2, the original position metal surface thickness that is compounded with TiN can reach 500 to 600 microns, and microhardness can reach more than the HV1700 to HV1800, even therefore in use there is wiping on the surface, still has good hardness and wear resistance;
