	1	Investigation on High Power Diode Laser Cladding of Ni-Fe-Cr Based Alloy Coatings显示文摘Appropriate laser cladding processing parameters for a Ni-Fe-Cr based alloy coating with good quality were studied using 3.5 kW diode laser.The characterization of the coating was investigated,and the influence of each parameter was analyzed.The mechanical properties and wear resistance of the coating were compared with the corresponding chemical composition wrought and cast materials.The results showed that a coating with aspect ratio about 3,dilution ratio 8%-10%and wetting angle 35o-50°could be formed with the laser power 1200-1500 W,travelling speed 8-10 mm/s,powder feed rate 16-18 g/min and shield gas flow 15 l/min.The tensile strength of the coating reached 953 MPa which was higher than that of wrought material 918 MPa and cast material 830 MPa.The microhardness of multi-layer coating was higher than that of single layer coating.The wear resistance of the coating was at the same level with the wrought and cast materials.

	3	Effect of Precipitation on the Microhardness Distribution of Diode Laser Epitaxially Deposited IN718 Alloy Coating显示文摘The microhardness distribution of the diode laser epitaxially deposited IN718 alloy coating was investigated.The Laves concentration in different regions of the coating was measured by binarization processing.The strengthening phase of the coating was characterized by transmission electron microscopy(TEM).The results showed that the microhardness increased along the depth of the coating.Part of Laves dissolved into austenitic matrix during the successive laser deposition.A little amount of strengthening phase was precipitated in the bottom region of the coating.It was attributed to the heat effect from the thermal cycle of successive deposition on the microstructure in the bottom region of the epitaxially deposited coating.
