Abstract

Powder metallurgy components are increasingly attractive in replacing cast materials for various applications. This occasionally requires the powder metallurgy parts to be joined to another material as integrated components. In this experimental work, the objective is to develop the powder metallurgy sintered bonding mechanism between premixed M3/II High Speed Steel powder(M3/II HSS) acting as cam lobe and the solid cast iron (as a shaft) which was formerly used for Proton Saga's 1.3 car camshaft. The base powder was characterized using Particle Size Analyzer in order to determine particle dimensions, X-ray Florescence (XRF) for elements composition, Scanning Electron Microscope (SEM) to observe the particles shape, X-ray Diffraction (XRD) for phase constitution existed in the powder, Differential Thermal Analysis (DTA) to determine the transformation temperatures experienced by the powder during the sintering process. Meanwhile the cast iron was analyzed using the Optical Microscope (OM) to observe the microstructure and SEM with Energy Dispersive X-ray attachment for the chemical composition. The powder was divided into 3 groups consisting of base M3/II HSS powder, M3/H HSS with addition of 5, 7, 8, 9, 10, 15wt.% copper and M3/H HSS with addition of 9wt.% copper and lwt.% phosphorus addition.
