Some high-strength structural parts have inclined shapes, such as gears, racks, and impellers. Nickel-based coatings are coated on the surface by laser cladding technology, which improves the mechanical surface performance and extends the service life of the parts. Regarding the geometric characteristics of inclined-matrix coatings, existing literature studies the deflection angles of nozzles, inclination angles of substrates, laser scanning methods, and overlapping ratios. Moreover, existing laser scanning methods include up-to-bottom, bottom-to-up, and horizontal continuous scanning for experimental comparative research.
