Coatings are extensively used in many areas including industrial and medical fields to serve various functions as corrosion resistance, wear resistance and antibacterial purposes. Copper and copper alloys are among the most widely applied coating materials for several industrial and medical applications. One of their widely used copper coating applications is in the antibacterial coating area. Most of the research done in this field focuses on the antibacterial behavior with no comprehensive assessment regarding their mechanical properties, such as hardness and adhesion strength. In this work, mechanical assessment of strength and hardness of pure copper and several copper alloys including Cu Sn5% P0.6%, Cu Ni18 Zn14 (German silver), and Cu Al9 Fe1 are studied experimentally and numerically. All coatings are deposited on stainless steel substrate disks of 25mm diameter by wire-arc thermal spraying at the center of advanced coating technologies, University of Toronto. All coatings are 150 microns in thickness, with two additional thicknesses up to 350 microns for Cu Ni18 Zn14 (German silver) and Cu Al9 Fe1. The effect of the coating thickness and composition on the mechanical properties is studied for all the copper and copper alloy samples with the varying thicknesses between 150 and 350 microns. Scanning Electron Microscope (SEM) is used to study the surface as well as the cross-sectional microstructure of the coatings. Vickers micro-indentation tests are used to evaluate hardness at various locations on the cross-section of the coating and the substrate. This is used to evaluate the effect of the deposition of the coating material, and the subsequent solidification, on the hardness of the coating layer as well as the substrate near the coating interface. Pull-off adhesion tests are performed to evaluate the effect of the coating composition and thickness on the strength of the coatings. Tests are carried out to compute the pull-off failure stress that causes the delamination between the coating and the substrate. Computational analysis will be used to calibrate the experimental data when available by means of finite element analysis. The preliminary pull-off tests show interesting results as the samples with lower coating thicknesses exhibit delamination at higher strengths. This is due to the increase in residual stresses in higher thicknesses building up during the deposition process. Some of the samples did not even fail at lower thicknesses of 150 microns. A comprehensive analysis between the adhesion strength and hardness will be very useful in understanding the effect of coating composition and thickness on the mechanical properties of the coating.

Hydroxyapatite (HAp) co-doped by magnesium (Mg), strontium (Sr), sodium (Na) and fluorine (F) were deposited on the 316L stainless steel (316L SS) substrate by electrodeposition method. The influences of scanning potential ranges, scanning times, scanning rates to form MgSrFNaHAp coating were investigated. The analytical results FTIR, SEM, Xray, EDX, thickness and adhension of the obtained coating at scanning potential ranges of 0 ÷ -1.7 V/SCE; scaning times of 5, scanning rate of 5 mV/s showed that MgSrFNaHAp coatings were single phase crystals of HAp, rod shape with the thickness 8.9 µm and the adhesion strength reached 8.38 MPa.

Austenitic stainless steel type AISI 316LN (316LN SS) material has been nitrided by three different nitride techniques such as Sursulf, Gas and Plasma nitriding. The 316LN SS samples have been prepared with two different surface roughnesses. The effects of surface roughness on nitriding with respect to formation of coating, case depth, increase in surface hardness and coating adhesion strength have been evaluated. The coating thickness was high for mirror polished samples than ground samples for all nitriding techniques. The coating thickness was very high (76.5µm) for plasma nitrided (PN) mirror polished sample and thin (22.5µm) & uneven for Sursulf Nitrided (SSN) ground sample. However, the SSN sample produces high surface hardness and good adhesion strength than PN. The Gas nitided (GN) sample produces the moderate result between SSN and PN.

To improve adhesion strength of DLC coatings on 304 stainless steel substrate,we studied substrate pretreatment by electrolytic/chemical etching methods.In this study,The DLC coatings were deposited on two groups of 304 stainless steel which had been electrolytically and chemically etched separately. The morphology of the coatings and substrate were characterized by SEM and metalloscope. The surface roughness of substrate was measured by roughness tester .The result shows that adhesion strength of DLC coatings on 304 stainless steel substrate is improved obviously due to mechanical interlock,surface adsorption and stress release.With prolonging the etching time,the adhesion strength of DLC coatings on the chemically etched substrate increase firstly and then decrease. The adhesion strength of DLC coatings on electrolytically etched substrate continuously increase. DLC coatings on electrolytically etched substrate perform better than the one on chemically etched substrate in adhesion.This is caused by the different surface morphology.

A silicon interlayer was introduced between the DLC films and 202 stainless steel substrate using a medium frequency magnetron sputtering. The adhesion was evaluated by the scratch tests and wear tests together. Two main parameters in the deposition process of Si interlayers, i.e. the sputtering current and pulse bias voltage, were optimized respectively, and the action mechanisms were discussed as well. Moreover, a special treatment with the purpose of forming a complete graded intermixed Si-Fe interface was designed to improve the adhesion strength further. DLC films with good adhesion strength were deposited on 202 stainless steel substrates using a silicon interlayer.
