Description
Technical field
The present invention relates to metal surface enhanced processing technology field.
Background technology
Titanium nitride (TiN) is a kind of non-stoichiometric compound, has the feature of Metallic Solids and covalent crystal simultaneously, and fusing point is up to 2955 DEG C.As top coat, the excellent comprehensive mechanical property such as TiN has high rigidity, wear-resistant, high temperature resistant, anti-thermal shock, frictional coefficient are low is current investigation and application one of thin-film material the most widely.TiN is successfully applied on the instrument such as cutter, drill bit as coating, is considered to the revolution in metal cutting tool technograph.
Technology of preparing mainly physical vapor deposition (PVD) and the chemical vapour deposition (CVD) at present of TiN coating.PVD method formation temperature is lower, coating is thinner, low with the bonding strength of matrix, and coating is easy to peel off from substrate, and poor around plating property.CVD depositing temperature is high, but has exceeded the thermal treatment temp of most Common Use Tools material, and the cutter material kind that thus can be used to carry out coating is very limited; Secondly, CVD is raw material with muriate, and need a set of equipment providing preparation to contain Ti halide gas, complex process, cost is higher, inconsistent with the green industry advocated at present.
No matter be PVD method or CVD, the TiN coating obtained is all thinner, and thickness only has several micron (μm), and coating and matrix are mechanical bond, and bonding surface intensity is low, uses floating coat easily to peel off.

TiN can be generated at metal surface In-situ reaction by above method, realize the strengthening to metallic surface and raising wear resistance.
The present invention has the following advantages:
1, TiN generates at metal surface In-situ reaction, instead of at surface deposition, therefore there is not the bonding force problem of coating and matrix;
2, In-situ reaction has the metal surface thickness of TiN to reach 500 to 600 microns, and microhardness can reach more than HV1700 to HV1800, even if therefore in use there is wiping on surface, still has good hardness and wear resistance;
