| Abstract | The present study reviews the tribological behavior of a Co-Cr-Mo alloy regarding to microstructural changes caused by solution and aged heat treatments. The influence of microstructure on wear resistance was assessed in a pin-on-disk configuration. It was found that after a long solution heat treatment of 6 h at 1200 °C, most of the carbides were dissolved into the matrix, and coarse grain size was obtained. Solution treatment for 1 h presented fine grains and globular carbides along the matrix. Aging at 850 °C resulted in a quantity of phase transformation which was different from austenite face cubic centered to martensite hexagonal close packed (HCP); 35% of HCP was reached during 8 h of treatment and 60% for 15 h. As-cast condition and 6-h solution heat treatment exhibited the greatest wear loss, while 1-h solution treatment and samples containing HCP phase showed a threefold lower wear. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
