Mechanical parts have a problem of wear when used in extreme environments. Aluminum, most used in the industrial field, is a representative material of light weight, but its wear resistance is not good. To resolve the wear problem of such materials, research and development of surface thin film deposition technology has been increasing. Wear resistance was investigated after the Ti thin film was deposited by sputtering, one of the main methods of this technique. The smaller the surface roughness value and the thicker the thin film, the better the wear resistance. However, when a thin film is deposited for a predetermined time or less, the bonding strength with the base metal is lowered and the wear resistance is confirmed as low.

Al7075的磨损特性随表面粗糙度和Ti薄膜沉积时间的变化而变化的研究

在极端环境下使用时，机械零件存在磨损问题。在工业领域中最常用的铝是重量轻的代表性材料，但是其耐磨性不好。为了解决这种材料的磨损问题，表面薄膜沉积技术的研究和开发一直在增加。在通过溅射沉积Ti薄膜后，研究了耐磨性，该技术是其中的主要方法之一。表面粗糙度值越小且薄膜越厚，耐磨性越好。然而，当在预定时间或更短时间内沉积薄膜时，与母材的结合强度降低，并且耐磨性被确认为低。
