Abstract

The absorption and dissemination of bacteria on the surface of medical equipment raises
the risk of human infections. The exterior surface of the surgical tools should have strong protection
against an unpropitious atmosphere. In the health sector, it is imperative to achieve the desired
durability and further ensure the safety and reliability of the surgical tools for surgery. The objective
of this review is to evaluate various properties of electroless Ni-P-TiO2 (ENPT) composite coating
with applying numerous modifications so that we can know the suitability of the ENPT composite
coating for the surgical tools properly. In this paper, ENPT composite coating has been modified in
several ways, some of them are by adding surfactants, TiO2 sol, and heat treated TiO2 nanoparticles
in the electroless plating solution. This review aims to make a comparative analysis of the surface
morphologies of these applied modifications and can enlighten us on the mechanisms behind the
changing behavior of the properties. The deposition characteristics of ENPT composite coating are
evaluated by scanning electron microscope (SEM), X-ray diffraction (XRD) to study the surface
morphology and crystal structure of the coatings respectively. The microstructure study of ENPT
coatings using the SEM image reveals the surface characteristics and pictorial concept of the
deposited surface. This review paper is aimed to summarize tribological properties, mechanical
properties and corrosion resistivity of ENPT composite coating. After evaluating and analyzing the
data, this article reveals which modification suits best for surgical tools applications
