Adhesion and mechanical properties of thin films examples

5 Adhesion and mechanical properties of thin films examples 

Over the years, the use of coatings such as HAp for implants and prostheses has gone from being a rarity to being an absolute necessity. A number of excellent studies on adhesion and mechanical properties have been carried out on a range of coatings major ones include HAp, diamond-like carbon (DLC), titanium nitride, titanium oxide, and nickel-titanium (Ben-Nissan et al., 2013). Listed below are some studies carried out on pure HAp and DLC thin films. 

The sol-gel technique is a preferred thin film fabrication method because of the relative ease of production and the inexpensive equipment used. Advantages of the process are based on its ability to form a physically and chemically pure and uniform coating over complex geometric shapes and the potential to deliver exceptional mechanical properties. 

Thin Fihn Coatings for Biomaterials and Biomedical Applications 

Early investigations of DLC coatings were plagued with problems such as decohesion and high compressive stress. To overcome the issue of coating delamination, the use of interlayers such as silicon-based materials was investigated to improve adhesion between DLC and metallic substrates (Bonetti et al., 2006).
