Production of Cobalt Chromium Molybdenum (CoCrMo) Foam by Replication Method
Cobalt Chromium Molybdenum (CoCrMo) generally known as a highly resistant to corrosion and wear performance. CoCrMo was prepared using replication method. The aim of this paper is to producing CoCrMo foam that will be given to consider the properties of CoCrMo foam after sintering process. The CoCrMo slurry was produced by mixing CoCrMo powder with Polyethylene Glycol (PEG) Carboxyl Methyl Cellulose (CMC) and distilled water. The polymeric foam template was impregnated in CoCrMo slurry and dried at room temperature. Sintering was carried out in a high temperature tube furnace at 1300degC. After the sintering process, the microstructure of the CoCrMo foam produced was observed by Scanning Electron Microstructure (SEM) and the elemental analysis was carried by Energy Dispersive X ray Spectroscopy (EDS) While, X Ray Diffraction (XRD) is used to characterize the chemical composition and structure of the samples. The EDS analysis performed in all samples with composition of 65 wt CoCrMo foam show the presence of of Cr, Mo, Co, Mn, C, O, Al, Si and Ca. From the XRD results, the pattern that was detected all the peak was PDF 2007: 00 041 0943(Cobalt Nitride)
