Characterisation of TiC-NiMo reinforced NiCrBSi hardfacing
In the present research, TiC-NiMo composites were remilled to particle size of 250-315 μm and used as reinforcements for NiCrBSi alloy by plasma transferred arc hardfacing process. The manufactured hardfacing alloy was characterised in terms of microstructure, mechanical properties and high temperature impact-abrasion wear resistance. Deposition results indicate high quality thick coating with uniform distribution of hard cermet (TiC-NiMo) particles in the matrix, minimum level of hard particles dissolution and low porosity of the hardfacing. Cermet particles stay in initial form and consist of agglomerates (TiC and (Ti,Mo)C grains) embedded into Ni-based matrix. The manufactured TiC-NiMo reinforced hardfacing alloy shows high impact/abrasion wear resistance with constantly low wear rates in the testing temperature range between 20℃ and 700℃.
