ABSTRACT
In this chapter, the scope of future work is discussed. Here, we want to show the new possibilities of the microplasma spraying (MIPS) process in the biomedical field.
In the previous chapters, we showed that the microplasma spraying method has proved to be more efficient in terms of retaining a high degree of crystallinity after the spraying, phase purity, and possessing of high porosity level without compromising the macro-as well as micromechanical properties, e.g., nanohardness and Young’s modulus. It has a unique microstructure to enhance the toughness and, to a relative extent, hinder the brittle crack propagation. It also shows no signature of large-scale delamination or rupture in a severe dynamic contact situation. In vitro followed by in vivo study established that the microplasma sprayed hydroxyapatite (HAp) coating also has the ability to heal bone defects in the animal model. Therefore, the MIPSHAp coating has established its potential for future application to human beings for bone defect healing and also stable cementless fixation. Further, in comparison to macroplasma spraying (MAPS), the MIPS process can lead to achievement of better properties in terms of crystallinity, phase purity, porosity, and reduction of residual stress.
