Notes:
This work presents aspects related to new sintered materials for valve seat insertsapplication. Two types of materials were evaluated. The materials were made using powdermetallurgy technique from a basic mixture of high-speed steel (AISI M3/2), iron and carbidepowders. The microstructures of these materials before and after heat treatment are presented.Under the heat treatment condition, the activation of the diffusion mechanism among phases waspromoted and a better distribution of the Cu phases along the matrix was achieved. The resultsindicate that the materials under development have a potential for commercial application as valveseat inserts
