dcterms:description
The properties of surface of biomedical implants made from CoCrMo alloy which are used as joint replacements have a fundamental influence on durability and functional properties of these implants. Surface texture parameters Ra and Rt are one of the important parameters which directly influences the durability of the coating and thus whole implant. The values of these parameters are given by standards ISO 7206-2:2011 and ISO 7207-2:2011. Three duplex surface systems were individually deposited to improve mechanical properties on the CoCrMo alloy. As a duplex treatment were used the combination of plasma nitriding process with subsequent depositing thin films of the coatings nACo3®, DLC and ZrN. The process of plasma nitriding of CoCrMo alloy was implemented under these conditions: duration time was 10 hours, the ratio of gases H2:N2 = 3:1 and process temperature 450 °C, 500 °C and 550 °C. The surface texture parameters Ra, Rt were measured on the polished surface of the CoCrMo alloy before plasma nitriding then on the polished surface after plasma nitriding and finally on the polished surface after depositing of coating. It was found that the deposition of selected coatings on the surface after application of plasma nitriding influences the surface texture parameters Ra and Rt.
