%X Laser surface modifying of as-cast Ni-based superalloy with Y-alloy pow-der was conducted and mictrostructure,phase composition,element profile of the layerformed have also been examined.The effects of laser processing condition on alloying pro-cess were discussed in relation to the distribution of element Y.It was inter ested to noticethat the reactive element Y existed in the alloyed layer along with element Al and it locallysegregates within the alloyed layer or in the top surface layer.
