dc.description.abstractThe scratch test plays an important role in the understanding of studies of tribological systems. It aims to contribute to the optimization of these systems in hot and cold conditions. There is a great demand for component failure due to wear to the hot condition, but the standardized indenter undergoes graphitization under these test conditions.Currently there is no standardized indenter that meets high temperature levels for the scratch test. In this work, he designed, fabricated and tested a carbide tool based on the requirements of ASTM G171-03. ASTM A36 steel was used as samples material, which were subjected to scratch, interferometry and hardness tests. A strong correlation tendency was found for values of coefficient of friction (Cof), hardness to risk (HSp), and the tool behaved not to wear. However, it did not reach loads higher than 70 N, and presented buckling in the course of the tests for this load.
