Abstract: |
Cemented carbides YG6 were pretreated by microblasting using white alundum abrasive of 45 μm, subsequently a gradient transition DLC film was deposited on by composite technique of anode laminar flow gas ion source and unbalanced magnetron sputtering. The surface contact angle, composition, phase and microstructure of samples before and after mircoblasting pretreatment were tested and analyzed. The results indicated that a significantly increased film adhesion strength and decreased frictional coefficient could be obtained by optimized microblasting pretreatment. The effects of microblasting pretreatment on property of DLC film were further discussed. |
