| Abstract [eng] |
Static friction is important for many non-lubricated surfaces, especially when friction is intermittent. Coefficients of Friction (COF) were evaluated on industrial aluminum alloys 1050 and 6082, which were freshly anodized in sulfuric/oxalic or phosphoric acid electrolytes to 60 μm coating thickness. Hard anodizing significantly reduced COF. Under 10 N load friction trends were nearly identical despite sliding velocity variation from 0.02 to 0.5 cm/s, while 1 N load led to higher static COF. Magnetron sputtering was used to deposit Ti layers. Static COF went down from over 0.4 to ~0.2 in 16 nm and 75 nm thick layers, while that of 2.3 µm had no positive effect. Dynamic COF was also similarly reduced, suggesting possible industrial applications. |
