| Abstract: | In this paper,the strengthening effect of laser remelting of three coatings by flame spraying has been investigated, the chemical composition,microstructure,construction and microhardness pf the coatings were stud ied before and after laser remelting. The wear test of the coatings was carried out. The experimental results show that the microstructure of the coatings is extremely fine and the quality of the coatings is improved obviously af ter laser remelting. The coatings have better wear resistance than aluminium-silicon substrate. |
