Laser cladding of Ni60/WC/TiN composite coatings on 00Cr13Ni4Mo hydro turbine blade stainless steel for improvement of wear resistance

摘要：

　　To improve the wear property of 00Cr13Ni4Mo hydro turbine blade stainless steel,Ni-based composite coatings were fabricated on 00Cr13Ni4Mo stainless steel by laser cladding using mixed powders of Ni60,WC and TiN.The microstructure of the coatings was characterized by XRD and SEM techniques.The wear resistance of the coatings was evaluated under dry sliding wear condition at room temperature.The results show that the coatings mainly consist of Ni-based solid solution,WC and TiN phases.The coatings exhibit excellent wear resistance due to its high hardness of WC and TiN phases.The main wear mechanisms of the coatings and the 00Cr13Ni4Mo sample are different,the former is abrasive wear and the latter is adhesive wear.
