MICROPLASMA SPRAYED HYDROXYAPATITE COATINGS

Features •Discusses plasma spraying and other related hydroxyapatite (HAp) coating techniques •Focuses on the pros and cons of macroplasma sprayed (MAPS)- and microplasma sprayed (MIPS)-HAp coatings •Provides a valuable reference for students, researchers, and practitioners of biomedical engineering and materials science Summary There has been enormous growth in the use of medical implants. However, in the case of hip replacement, loosening of metallic prosthesis fixed with polymethylmethylacrylate bone cement has resulted in painstaking revision surgery, which is a major problem for the patient, surgeon, and biomedical technology itself. Global recognition of this problem led to the development of cementless fixation through the novel introduction of bioactive hydroxyapatite (HAp) coating on biomedical-grade metallic implants. Since then, a wide variety of coating methods have evolved to make HAp coatings on metallic implants more reliable.
