บทคัดย่อ

Particle contamination is a major problem in the hard disk drive manufacturing industry, and the tightening of screws during the manufacturing process has been found to be one of the main sources of particles. The aim of this research is to study the possibility of using molybdenum disulphide titanium composite (MoS2T) coating to reduce stainless steel particles that are generated in screw tightening process in hard disc drive assembly. The experiments used for simulating dry sliding wear mechanisms were carried out by TriboGear machine. The machine consists of a stationary bit loaded against the plate containing screw. The screws used were made of martensitic 410 stainless steel and the bit was made of S2 tool steel. MoS2T film was coated on S2 tool steel bit and martensitic 410 stainless steel screw, the film was deposited by sputtering technique with film thickness of 1.0 ตm. Dry sliding wear mechanisms were simulated both under single and loading cycle contacts wear. The tests were conducted under normal load corresponding to the effective stresses that are higher and lower than the yield strength of screw material. The results showed that the use of solid lubricant MoS2T coating is capable of total prevention of generation of stainless steel particles due to adhesive wear. This study also shows that no stainless steel particles were found on the carbon tape suggesting that no particles were generated for single loading test. However, the coating showed surface wear with film gradually peeling off during loading cycle contact wear experiments. ฉ 2016, ICE Publishing. All rights reserved.
