Laser cladding has been developed as a useful technology to modify material surface in industry. In this paper a new approach of surface modification is introduced. Depositional Laser Cladding (DLC) was developed and the different mechanisms were investigated during the manufacture. Basing on particular analysis of defects in the experiment, the relation between the quality of cladding layer and laser energy density is manifested. Depositional effect and thermal effect play their roles in different place and the depositional effect provides thin layers with the thickness of near mean particle size. Appropriate parameters of laser energy can promote high quality, avoiding pores and stacks in agglomeration and ebullition. Controllable low thickness near mean particle size and sharp edge make it possible to be used on producing certain shape in the surface engineering field, such as restoring and gradient materials.
