    摘要： The laser nitriding method of making phosphor bronze with surface-embedded titanium carbide particles involves coating a cleaned phosphor bronze workpiece with a thin film formed of a carbonaceous layer mixed with nanosize particles of titanium carbide. The titanium carbide forms about 5 wt % of the thin film, and the phosphor bronze workpiece is composed of about 6.0 wt % tin, about 0.1 wt % phosphorous, and about 93.9 wt % copper. A laser beam is then scanned over the thin film formed on the phosphor bronze workpiece. Coaxially and simultaneously with the laser beam, a stream of nitrogen gas is sprayed on the thin film formed on the phosphor bronze workpiece in order to provide the workpiece with a nitride coating having nanoparticles of titanium carbide embedded therein.

    摘要： A method of laser treating a zirconia surface can include surface texturing zirconia using a combination of ablation and melting. The method includes forming a carbon film on the zirconia surface and laser treating the carbon-coated zirconia surface. The carbon film can include titanium carbide (TiC) and boron carbide (B4C), for example. The carbon film can include titanium carbide (TiC) and boron carbide (B4C) in equal proportions. The carbon-coated surface can then be scanned with a nitrogen gas-assisted CO2 laser beam to form a laser-treated surface. The laser-treated surface can include ZrN compounds. The present method can enhance the surface properties of zirconia and improve the structural integrity of zirconia.
