Iron Based

TiC and TiB 2 reinforced iron based metal matrix composite (MMC) coating was synthesized on mild carbon steel by laser cladding employing B 4 C , ferrotitanium, and FeCrSiB mixed powders. The microstructure and chemical composition were analyzed by means of SEM, EPMA, and XRD. Results show that the coating mainly consists of α– Fe(Ni) , TiB 2, TiC , B 6 Fe 23, Cr 2 B , and M 23 C 6. TiB 2, and TiC reinforcements are formed in situ through the reaction between B 4 C and ferrotitanium. Hardness and wear measurement results show that the hardness and wear resistance of the composites are much higher than that of the as-received sample.

Heterogeneous Phase

The TiC/Ni composite coating was prepared by Laser Cladding In-situ Synthesis on the surface of damper plate with Ni--Ti-Mo-C -LaF3 powder．Microstructure and Wear resistance have been studied throughout EPMA、SEM and M—2000 Friction and Wear Tester．It was found that the microstructure got more homogenized grain fineness became finer, TiC distributed better and heterogeneous phase decreased, as adding moderate rare earth LaF3. When the content of LaF3 was 1%, the highest microhardness was got. While the optimal wear resistance properties were obtained with 2% LaF3. The laser cladding with excessive LaF3 has more TiC particle segregation which induces hardness and wear resistance of cladding layer.

Mild Steel Substrate

Ni-Al intermetallic compound coatings no visible cracks, pores or inclusions are prepared on mild steel substrate by Laser- cladding in situ synthesis with mixed powders of nickel-coated aluminum, Ni-based alloy and Al. The results show that the microstructure of the coating consists mainly of two phases of NiAl and Ni3Al, and the former amount is more than the latter, with NiAl being uniformity and staggered fine dendrites which are surrounded continuously by Ni3Al, and the atom ratios of Ni∶Al∶Fe∶Si in NiAl and Ni3Al are respectively 54∶39∶2∶5 and 70∶21∶3∶6. Compared with cladding nickel-coated aluminum, the coatings quality are improved, and the dilution of iron from substrate into coating are greatly reduced, as a result of lower cladding powers due to self-fluxing of Ni-based alloy and exothermic reaction between Ni and Al. The hardness of coatings are up to HV490-HV540.
