Investigation Of Friction And Wear Characteristics Of Palm Biodiesel Mar 2013

Investigation Of Friction And Wear Characteristics Of Palm Biodiesel

A.S. Md Abdul Haseeb

Use of biodiesel in automobile engine is creating tribology related new challenges. The present study aims to assess the friction and wear characteristics of palm biodiesel at different concentration level by using four-ball wear machine. The investigated fuels were biodiesel (B100), diesel (B0) and three different biodiesel blends such as B10 (10% biodiesel in diesel), B20, B50. Tests were conducted at 75 °C under a normal load of 40 kg for 1 h at four different speeds viz, 600, 900, 1200 and 1500 rpm. Worn surfaces of the balls were examined by SEM. Results showed that wear and friction decreased …

The Wear Behavior Of Cross-Linked Uhmwpe Under Dry And Bovine Calf Serum-Lubricated Conditions Jan 2013

The Wear Behavior Of Cross-Linked Uhmwpe Under Dry And Bovine Calf Serum-Lubricated Conditions

A.S. Md Abdul Haseeb

The present study was performed to investigate the effects of gamma radiation on the wear behavior of unirradiated and irradiated ultra-high-molecular-weight polyethylene (UHMWPE) against Ti-6Al-4V under dry and lubricated conditions at different applied loads. The UHMWPE specimens were exposed directly to nominal doses of 0, 25, 40, 50, and 100 kGy. Scanning electron microscope (SEM) analysis of the worn surface of UHMWPE and Ti-6Al-4V was performed to understand the mechanism of wear involved between the contact surfaces during wear testing. From the wear test results, there were significant differences between the wear of unirradiated UHMWPE and UHMWPE irradiated at 25, …
