The reinforcing method takes TiO2 and N2 as components. TiO2 powder is coated on the metal surface, and the laser superposed tungsten electrode gas-shielded arc is used to scan the metal surface coated by the TiO2 powder in an N2 atmosphere. According to the reinforcing method, TiN is generated on the metal surface layer in an in-situ composite manner; the metal surface is reinforced; and the wear resistance of the metal surface is improved.
Description
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.
