“…Variasi dari gesekan dan laju keausan ini sangat tergantung dari kondisi pengujian seperti: normal load, geometri, relative surface motion, sliding speed, surface roughness, type of material, system rigidity, temperature, lubrication dan vibration [14]. Pada penelitian ini akan dilihat mode keausan abrasive (abrasive wear) dengan menggunakan persamaan specific wear rate seperti diperlihatkan pada persamaan 1 [15]…”

Penelitian ini dirancang untuk mengevaluasi kualitas oli pelumas sepeda motor dalam mengatasi gesekan dan keausan yang terjadi. Banyak merek dagang oli pelumas yang ada di pasaran dengan berbagai standard seperti SAE, JASO dan API yang bertujuan untuk melumasi bagian dalam mesin sepeda motor. Oleh sebab itu mengetahui kualitas oli pelumas yang digunakan adalah hal yang sangat penting. Penelitian ini menggunakan metode pin-on ring tribo tester. Efek dari pelumasan dan jumlah beban yang diberikan menjadi fokus dalam penelitian ini. Material yang digunakan dalam pengujian adalah aluminium sebagai bahan pin dan besi cor digunakan sebagai bahan ring. Sedangkan oli pelumas dari SAE10W40, SAE20W50 untuk gesekan tinggi dan SAE10W30, SAE20W40 untuk gesekan rendah. Prosedur pengujian dikondisikan pada constant load dan increment load dalam durasi waktu 120 menit. Hasil dari tribological test ini dibandingkan dengan stribeck curve dan keausan pin serta koefisien gesek ditampilkan dalam bentuk grafik. Kata kunci: keausan; pelumas; sepeda motor; standard oli; tribo tester.

“…For 2 and 5N loads, it appears that the wear mechanism change. The initial wear is certainly due to the time required to ensure that the system is in a stationary wear state [43]. The second stage corresponding to stationary wear can be qualified as abrasive wear governed by the laws discussed above.…”

The Tribological behavior of Polystyrene Crystal disc sliding against a steel 100Cr6 ball with a radius of 5mm over a range of loads (1-5N) and speeds (12.5-63mm/s) was investigated using a ball-on-disc tribometer under unlubricated conditions. All the specimens were used as obtained from injection molding. For this purpose, we monitored the evolution of the friction coefficient and the wear rate as a function of sliding speed and normal load applied. The worn surfaces were examined by Scanning Electron (SEM) and optical microscope. Several wear mechanisms were observed: plastic deformation, abrasion in the track, and adhesion at the edge of the track. The mechanisms were found to depend on speed and load. The wear rate is of the order of 10-2mm3/N.M, which may explain that the wear is of a severe type.

“…Surface planarization, which increases the actual contact area while reducing the local contact stress of sliding interfaces, has considerable potential in the optimization of tribological performance. − Herein, we presented a polishing approach for considerably improving the lubricating properties of PPI in an oil-impregnated state. The mechanisms of surface polishing to reduce friction and suppress surface wear with blackening products forming on the PPI surface were elucidated using U-tube absorption studies and energy dispersive X-ray spectroscopy (EDS).…”

Because of its self-lubricating qualities, porous polyimide (PPI) has been used as a crucial cage material for space bearings; however, overcoming the failure followed by blackening of PPI remains a challenge. Herein, we developed a surface smoothening approach to optimize the tribological performance of PPI in an oil-impregnated state. Pre-polishing using sandpaper and then with Al2O3 paste enables the fabrication of nanoscale rough PPI surfaces with significantly reduced friction and surface wear and complete suppression of the blackening phenomenon. Compared with polishing using sandpaper or Al2O3 paste, the compound polishing method created a substantially smoother surface. It exposed more polytetrafluoroethylene at the outermost surface, improving the liquid and solid lubrication properties of the contact interface under a mixed lubrication state. The further analysis indicated that decreasing the size of PPI surface pores during pre-polishing using sandpaper was crucial in resisting the adsorption of residual polishing particles.
