中文摘要
The microstructures of laser cladding of (Ni-24.5%(atom fraction)Al)+50%(mass haction)WC coatings before and after aging was comparetively studied by using SEM and TEM. It is shown that dissolving of WC and reprecipitating in the forms of WC and W2C occurred during laser cladding, and intermetallic γ' (Ni3Al) orderly precipitate from metastable supersaturant Ni-matrix solid solution after heat treatment. The structures are favorable for coating's properties.
