Adding a low content of soft metals (such as Ag, Au, Cu, etc) in TiN-based films can decrease the friction coefficient of the nitride films. To improve the mechanical properties of the TiAlSiN film, 4.5 at.% Ag was added in the TiAlSiN film. TiAlSiN and TiAlSiN/Ag films were deposited on AISI304 steel by magnetron sputtering using a Ti50Al40Si10target and a Ti50Al40Si10plus an Ag strip, respectively. The microstructure and mechanical properties of the films were investigated by SEM/EDS, XRD, a tribological machine and a microhardness tester. The results show that, with 4.5 at.% Ag addition, the surface morphology of the TiAlSiN film became rougher and its microhardness decreased from 1520±35 HV0.01to 1307±42 HV0.01. The preferred orientation of (111) of the TiAlSiN film changed to randomly and the diffraction peaks became broader due to the Ag addition. The friction coefficient of the TiAlSiN-Ag film decreased compared with the TiAlSiN film, but it showed inferior wear resistance due to its lower microhardness. The effects of Ag addition on the microstructure and mechanical properties of TiAlSiN films were discussed.

AbstractNi-based alloy coatings prepared by laser cladding has high bonding strength, excellent wear resistance and corrosion resistance. The mechanical properties of coatings can be further improved by changing the composition of alloy powders. This paper reviewed the improved microstructure and mechanical properties of Ni-based composite coatings by hard particles, single element and rare earth elements. The problems that need to be solved for the particle-reinforced nickel-based alloy coatings are pointed out. The prospects of the research are also discussed.

W(100-x)%Cx% coatings with different tungsten and carbon contents were deposited by unbalanced magnetron sputtering. The microstructures and mechanical properties of the W(100-x)%C x% coatings was characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), nanoindentation and adhesion testing techniques. The tribological performance of the coatings was investigated using a pin-on-disc trobometer under dry conditions. Experimental results indicated that coating microstructure, mechanical properties and wear resistance varied according to the tungsten and carbon contents of the coatings. The W72%C28% coating had the highest hardness/elastic modulus (H/E) ratio. In the ball-on-disc wear tests, it was found that the W72%C28% coating exhibited the best wear resistance.

Ag-doped hydroxyapatite films were deposited on a ZrO2 substrate using r.f. magnetron sputtering to improve the bioaffinity and mechanical properties of the hydroxyapatite. The resulting hydroxyapatite films exhibited a variation in their microstructure and mechanical properties relative to the Ag content. The variation in the (Ca, Ag)/P ratios suggested that some of the Ca2+ ions in the hydroxyapatite were replaced with Ag+ ions. After annealing at 800oC, the hydroxyapatite films showed a microstructure with crystalline nano-grains, whereas the Ag-doped hydroxyapatite films revealed the formation of crystallites embedded in the amorphous matrix. The hydroxyapatite films showed an average roughness of about 3~4nm, very smooth surface, and dense microstructure. The hardness and modulus of the films decreased with an increasing Ag content.
