A diode pumped Ytterbium fibre laser used to clad TiB2/TiC/Al onto the surface of aluminium alloy EN AW-6082-T651. Aluminium was added to TiB2-TiC ceramic precursor mixture to improve adhesion of the ceramic coating to the substrate, whereby retaining the characteristics of the ceramic components. The resulting coating was studied by means of a microstructural and mechanical analysis. Good adhesion of the coating to the substrate with no cracks and low porosity was observed. Microhardness in the coating is 82 % higher than uncoated alloy. Wear resistance of the coated surface was found to be 8 times higher when compared to the uncoated alloy. The coefficient of friction was found to be 0.57. [ABSTRACT FROM AUTHOR] |
