The Cubic boron nitride (CBN) coating are prepared by laser cladding on the TC11 surface.The hardness of cladding coating were researched by means of mechanical property testing.The result indicated that the coating micro-hardness increases with increasing laser power when the other parameters are fixed.With the laser power increasing,Injection of energy increases,The reinforced phase increased,microhardness along with it enhancement.With the increase of the scanning speed within chose, the microstructure of the cladding layer changes tiny and uniform,the microhardness were increased,The hardness was increased greatly which after Laser hardening. The maximum values of them are as about five times as that of the substrate.

Microstructure Of The Material

The allotropes of boron nitride include two sp2-bonded phases with hexagonal and rhombohedral structures (hBN and rBN) and two sp3-bonded phases with cubic (zincblende) and hexagonal (wurtzitic) structures (cBN and wBN) (Fig. 1). Although cBN is synthesized in bulk form by conversion of hBN at high temperatures and pressures, low-pressure synthesis of cBN as a thin film is more difficult and succeeds only when the growing film is simultaneously irradiated with a high flux of ions. Only sp2-bonded material, which generally has a disordered, turbostratic microstructure (tBN), will form in the absence of ion-irradiation. The mechanistic role of the irradiation is not well understood, but recent work suggests that ion-induced compressive film stress may induce the transformation to cBN.Typically, BN films are deposited at temperatures less than 1000°C, a regime for which the structure of the sp2-bonded precursor material dictates the phase and microstructure of the material that forms from conventional (bulk) high pressure treatment.
