摘  要:
An investigation on iron cast surface pretreatment before arc spraying was made with quadratic regression rotary combination test. The mathematical model that characterizes the relationship between parameters of grit blasting (blasting distance, blasting pressure and blasting angle) and adhesive strength between coatings and substrate was established. The influencing law was studied by decreasing dimension and the results show that the effects of distance and pressure are great and the effect of angle is small. It is reliable for adhesive strength between coatings and substrate and the technology of grit blasting can meet the demand of surface pretreatment for arc spraying.
