Solid state sintering of Co-Cr-Mo (F 75): Microstructure and properties
(SIRIM, 2010-11-22)
The influence of sintering temperature to the physical properties of P/M Co-Cr-Mo (F-75) alloy
(Universiti Malaysia Perlis, 2009-12-01)
Co-Cr-Mo (F-75) alloys are commonly used for surgical implants because of their strength, corrosion resistance and biocompatibility. Conventionally, fabrication of the alloys has been established using casting technique. ...

The influence of welding parameters and corrosive environment on the joint strength of resistance spot-welded mild steel sheets
(University of Malaya, 2009)
In the present work, mild steel sheets consisting two batches were welded by resistance spot welding at different welding parameters and exposed under different environments. The 5% sodium chloride brine was used in the ...
Palm Ash as an Alternative Source for Silica Production
(EDP Sciences, 2016)
Agricultural wastes such as palm ash and rice husk have a possibility to be used as a useful renewable source for the production of silica (SiO2). Extensive researches have been carried out to extract silica from agricultural ...
