This work aims to study the effect of mechanical treatment technique on titanium coated with PVD for the enhancement of corrosion resistance for the biomedical implant. First, substrates were coated with TiN via PVD then applied the mechanical treatment through ultrasonic vibration. Results show that all coated samples treated with ultrasonic vibration improve the surface of the coated sample and produce a compact coating as compared with a substrate coated without mechanical treatment. The corrosion test evaluated by Potentiodynamic polarization and Electrochemical Impedance Spectroscopy indicated that all coated samples treated with mechanical treatment showed high corrosion resistance as compared with the untreated sample. It can be concluded that mechanical treatment which is a simple technic can be used as an alternative to improve the corrosion resistance thus reduce the implant and manufacturing cost for biomedical applications. ?

Surface modification techniques have been proven to enhance resistance towards corrosion, to slow the process of wearing, to reduce metal ions release, as well as the process of biomaterial osseointegration. Not only that, these techniques could extend the longevity in materials related to implant, primarily because of its response towards the host of body. Generally, these techniques can be further broken down into physical, mechanical, and chemical approaches. As such, this paper presents further information pertaining to the numerous types of methods for modifying surfaces, along with their benefits and drawbacks. Additionally, several other significant aspects are detailed as well in this paper, for example, the materials and biomaterials used for implant, as well as a number of issues concerning the usage of alloy, biomaterial and titanium. ? 2018 Elsevier Inc.
