Abstract

In many applications such as cylinder body, sleeve and mould side wall, vertical surfaces need to be strengthening together with horizontal surfaces. In this paper, a new powder feeding nozzle for laser vertical surface treating was designed and a whole laser surface modification system with powder feeding for vertical surfaces is developed. By using this system, experimental work on laser remelting, laser alloying with powder feeding, laser cladding with powder feeding was performed on vertical surfaces of gray iron substrates. The microstructure, composition and hardness distribution were analyzed. The results indicate that the properties of the vertical surfaces have been greatly improved after these treatments. The powder feeding nozzle and vertical processing can realize various vertical surface modifications with or without powder feeding, which has a promising prospect in industry applications.
