Abstract
The invention discloses a method for strengthening the compounding of TiC on a laser-induced metal surface layer taking TiO2, carbon black and acetylene as components and relates to the technical field of metal surface strengthening. The method comprises the following steps of: coating the mixed powder of TiO2 and the carbon black on a metal surface; and scanning on the metal surface by using a laser beam at the acetylene atmosphere, wherein the mixed powder of TiO2 and the carbon black is coated on the metal surface. Through the method, TiC can be generated on the metal surface layer through in-situ compounding so that the metal surface is strengthened and the wear resistance is improved.
Description
Technical field
The present invention relates to the intensifying technology field of metallic surface.
Background technology
Titanium carbide (TiC) is typical transition metal carbide, and of bonding is blended in the same crystalline structure by ionic linkage, covalent linkage and metallic bond, and fusing point is up to 3160 ℃.As top coat, TiC has the good comprehensive mechanical properties such as high rigidity, high-melting-point, wear-resistant, high-temperature oxidation resistant, is one of thin-film material of studying at present and being most widely used.
The technology of preparing of TiC coating mainly is chemical vapour deposition (CVD) and physical vapor deposition (PVD) at present.CVD method depositing temperature is high, has surpassed the thermal treatment temp of most steel, and CVD is take muriate as raw material, the equipment that needs a cover to provide preparation to contain the Ti halide gas, and complex process, cost is higher, and is inconsistent with the green industry of present promotion.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.
No matter be CVD method or PVD method, the TiC 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 with TiO
2, carbon black and acetylene is the induced with laser metal surface composite Ti C enhancement method of constituent element, can make matallic surface layer original position composition generation TiC, thereby wear resistance is strengthened and improved in the metallic surface.
The present invention is achieved by the following technical solutions:
At metallic surface coating TiO
2With the mixed powder of carbon black, in the atmosphere of acetylene, use laser beam at deposited TiO
2Scan with the metallic surface of the mixed powder of carbon black.
Can at metal surface original position composition generation TiC, realize reinforcement and raising wear resistance to the metallic surface by above technique.
The present invention has the following advantages:
1, TiC 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 TiC can reach 500 microns, and microhardness can reach more than the HV2600, even therefore in use there is wiping on the surface, still has good hardness and wear resistance;
