This work presents and discusses the extreme-pressure properties of binary oil mixtures made with a low viscosity polyalphaolefin (PAO 6) and two esters (TMP-05 and sunflower oil, SO). Tests were made in a four-ball machine tester using the ASTM D 2783-88. The ball test material was AISI 52100 steel, 12.7 mm. in diameter, with a hardness of about 65 HRC. The wear scar diameter (WSD) was measured with an optical microscope. The results showed that: although PAO 6, TMP-05 and SO have different physical properties, they perform similar behavior under high loads; TMP-05 and SO have better results in wear tests than PAO 6, but their extreme-pressure properties are similar; and TMP-05 and SO act as wear reducers when they are added to PAO 6, but they do not improve its behavior under high loads.

Abstract TIMKEN TBS-9 is a high-carbon, chromium-molybdenum ball-bearing steel that combines high hardenability and low cost. It was designed with metallurgical properties virtually equivalent to those of AISI 52100. TBS-9 is less expensive than the 52100 grade because annealing is simplified. It is produced to the same quality requirements as the 52100 steel. This datasheet provides information on composition, physical properties, hardness, and elasticity as well as fatigue. It also includes information on forming, heat treating, machining, and surface treatment. Filing Code: SA-363. Producer or source: Timken Company Steel Divison.

Abstract Schmelzmetall Hovadur CCZ is a heat-treatable, copper-chromium-zirconium alloy. In the solution heat-treated and artificially aged condition, this alloy exhibits high thermal and electrical conductivity along with high strength and a high softening temperature. Hovadur CCZ evolved from CuCr1 (CW105C), a precipitation-hardenable alloy first made in the 1930s for spot welding electrodes, for which strength and hardness at temperatures up to 500 °C (930 °F), as well as good electrical and thermal conductivity, are essential. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on forming, heat treating, machining, and joining.

Particles Dynamics

Micro-abrasion remains a test configuration hugely used, mainly for thin coatings. Several studies have been carried out investigating the parameters around this configuration. Recently, a new study was launched studying the behavior of different ball materials in abrasive particles’ dynamics in the contact area. This study intends to extend that study, investigating new ball materials never used so far in this test configuration. Thus, commercial balls of American Iron and Steel Institute (AISI) 52100 steel, Stainless Steel (SS) (AISI) 304 steel and Polytetrafluoroethylene (PTFE) were used under different test conditions and abrasive particles, using always the same coating for reference. Craters generated on the coated samples’ surface and tracks on the balls’ surface were carefully observed by Scanning Electron Microscopy (SEM) and 3D microscopy in order to understand the abrasive particles’ dynamics. As a softer material, more abrasive particles were entrapped on the PTFE ball’s surface, generating grooving wear on the samples. SS AISI 304 balls, being softer than the abrasive particles (diamond), also allowed particle entrapment, originating from grooving wear. AISI 52100 steel balls presented particle dynamics that are already known. Thus, this study extends the knowledge already existing, allowing to better select the ball material to be used in ball-cratering tests.
