the feasability of surface treatments by cw yag laser has been established. concerning solid phases treatment, the authors explored superficial quenching of grey cast iron. it brings out that it's not necessary to precast the sample before treatment, the natural absorptivity is sufficient. concerning liquid phase transformation two examples are presented' surface alloying and cladding. for the first one, the power required for a given melted depth is 2 times lower than for a co/sub 2/ beam. concerning the second example, it appears that the use of a step index fiber could improve obtained results. finally from a metallurgical point of view, obtained structures are the same as with a co/sub 2/ beam
