Microstructure and Properties of AlSn20 Coating Deposited via Magnetron Sputtering

Abstract:

In view of the present reality of sputtered plating bearings imported in our country, unbalanced magnetron sputtering deposition techniques was used to fabricate AlSn20 anti-friction coating on aluminum bearing alloy. Microstructure characterization of the coating was performed by SEM. Micro-hardness testing of Coating were measured with a Vickers indenter. Adhesion testing was carried out with a scratch tester. Wear and friction tests were performed with a pin-on-disc tribometer. The results revealed that the AlSn20 anti-friction coating (bias voltage in the range of-60V~-100V) showed finer crystal, better corrosion resistance (E_corr=-1.25V), higher hardness (up to 80HV0.025), better adhesion with substrate (up to 35N), and lower friction coefficients down to 0.15.
