Reports from National Research Council of Canada Highlight Recent Findings in Surface Science and Engineering

May 28, 2014



By a News Reporter-Staff News Editor at Journal of Engineering -- Investigators publish new report on Surface Science and Engineering. According to news reporting from Ottawa, Canada, by VerticalNews journalists, research stated, "A sintered Co-Cr-Mo/Bioglass() composite coating, developed for medical implant application, is examined and compared to plasma-sprayed and sintered monolithic Co-Cr-Mo coatings. In addition to microstructure and wear resistance analysis, the bioactivities and corrosion behaviours of various coatings are assessed using simulated body fluid (SBF) immersion."

The news correspondents obtained a quote from the research from the National Research Council of Canada, "The sintered Co-Cr-Mo/Bioglass() composite and monolithic Co-Cr-Mo coatings have more porous structure than the plasma sprayed Co-Cr-Mo coating. Although the Co-Cr-Mo/Bioglass() composite coating has adequate bonding between Co-Cr-Mo powder and glass particles, the wear resistance is lower than the plasma sprayed Co-Cr-Mo and Stellite 21 substrate. After SBF immersion, calcium is present on the Co-Cr-Mo/Bioglass composite coating, but not on the Co-Cr-Mo coating."

According to the news reporters, the research concluded: "It indicates the formation of an apatite layer on the Co-Cr-Mo/Bioglass composite coating and potentially better bioactivity than the monolithic coatings."
