Study of the adhesion of nc-TiC/a-C:H coatings on plasma-treated steel substrates
Original language description
Nanocrystalline titanium carbide embedded in an hydrogenated amorphous carbon matrix (nc-TiC/a-C:H) shows high hardness and Young's modulus together with low wear and low friction coefficient. The adhesion of nc-TiC/a-C(:H) films to industrially attractive substrates is often poor, therefore an adhesion promoting interlayer is routinely introduced to overcome this problem. The aim of the recent work is to study the adhesion of nc-TiC/a-C:H coatings to high speed steel substrates. The coatings were deposited by the hybrid PVD-PECVD process using the unbalanced configuration of the magnetic field. The substrates were treated by several methods including chemical, mechanical and plasma techniques. The influence of the cleaning time and bias voltage on thesubstrate holder on the resulting adhesion was studied. In addition titanium interlayers with various thicknesses were deposited on the substrates prior to the coating deposition in order to study its adhesion as a function of the interl
