To analyze the mechanisms of tribochemical reactions occurring between atmospheric gases and materials induced by friction, the authors have developed a friction test system with integrated XPS. The system can analyze worn surfaces in various environments using XPS without air exposure. The results of friction tests in vacuum showed that the native oxide film that formed on the bare surface was worn by friction in vacuum. The results of the friction tests in an Ar gas atmosphere also showed the same results as the friction tests in vacuum. However, it has been suggested that some tribochemical reactions with trace amounts of residual gas occur during friction tests in an Ar gas atmosphere. The results of the friction tests and XPS analyses indicated that our friction test system with integrated XPS was useful for analyzing tribochemical reactions between atmospheric gases and materials.

Tribological Performance of Copper-Titanium Alloy under Dry Sliding Contact

Frictional heating leads to sparking and excessive wear of components in engineering applications. Until now, copper-beryllium alloys have been used extensively in frictional contacts where nonsparking ability is desired. However, copper-beryllium creates an inhalation hazard when there is exposure to the dust or fumes from beryllium metal, metal oxides. Besides nonsparking ability, an environmentally friendly alternate material having equally good electrical and tribo-mechanical properties needs to be developed. In achieving the objective of this article, tribological properties of copper titanium alloy as an alternative under dry sliding contact were investigated and compared. Experiments were conducted on copper-titanium alloy having 2 % and 4.2 % titanium sliding against an EN-31 disk using a pin-on-disk apparatus. Taguchi-based design of experiments was used to find out significance of parameters and their effect on friction coefficient and wear rate. The microstructure was studied for distribution of titanium powder in alloy and its effect on grain distribution vis-à-vis tribo-properties using scanning electron microscopy analysis. It was found that the coefficient of friction decreases as titanium concentration and velocity increase. Titanium concentration has a significant effect on reducing wear. Results are indicative for potential use of copper-titanium alloy instead of copper-beryllium alloy. Because copper-titanium is a more recent material, its tribological properties are yet to be researched. Apparently, hardly any literature is available exclusively in this type of application.

Disks of ferrous and titanium-based material were immersed and unidirectionally slid against a stainless steel pin in ethanol with or without acetic acid to evaluate the effect of acetic acid on wear. The disks were made of cast iron, stainless steel, titanium metal and particulate-reinforced titanium metal matrix composite sintered from mixed powder of Si 3 N 4 (5 mass%), TiN (10 mass%) and Ti (85 mass%). In the absence of sliding, the stainless steel, titanium and composite showed good corrosion resistance but the cast iron exhibited galvanic corrosion. With sliding, the addition of acetic acid to the ethanol increased the wear of the ferrous materials but had little effect on the titanium-based materials. Morphological and chemical analyses of the worn surfaces revealed that acetic acid promoted anodic dissolution of iron on the sliding surfaces of the ferrous materials in ethanol. The results also indicated that titanium and the composite in ethanol with and without acetic acid primary underwent mechanical wear and chemical wear, respectively. The composite exhibited good corrosion and wear resistance in ethanol regardless of the presence of acetic acid.
