Improve the Wear Resistant Life of the Sprag Clutch by Used the Chemical Vapor Deposition Technology
In order to improve the wear resistance of the sprag clutch under the work condition, the chemical vapor deposition technology is used on the surface of sprag. The hardness of surface is HV0.11700~2300, the thickness is 5~8μm, and the adhesion force isn’t less than 65N. In the end, the wear resistant life of the sprag surface used the chemical vapor deposition process is improved 5 times than that of the sprag surface used the physical vapor deposition process by the low cycle fatigue test. The life of the sprag clutch is effectively improved.
