Microplasma Sprayed Hydroxyapatite Coatings by Dey, Arjun; Mukhopadhyay, Anoop Kumar;

Short description:

This valuable reference discusses plasma spraying and other related hydroxyapatite (HAp) coating techniques, focusing on the pros and cons of macroplasma sprayed (MAPS)- and microplasma sprayed (MIPS)-HAp coatings. The book examines the structural, chemical, macromechanical, micro/nanomechanical, and tribological properties and residual stress of HAp coatings. It evaluates the efficacies under simulated body fluid immersion for MAPS- and MIPS-HAp coatings developed on biomedical implant-grade SS316L substrates. It also surveys in vivo studies of MIPS-HAp coatings, presenting the results of pioneering research related to bone defect fixation.

Long description:

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. In fact, global recognition of this problem led to the development of cementless fixation through the novel introduction of a bioactive hydroxyapatite (HAp) coating on biomedical-grade metallic implants. Since then, a wide variety of coating methods have evolved to make the HAp coatings on metallic implants more reliable.

Microplasma Sprayed Hydroxyapatite Coatings discusses plasma spraying and other related HAp coating techniques, focusing on the pros and cons of macroplasma sprayed (MAPS)- and microplasma sprayed (MIPS)-HAp coatings. The book begins by explaining what a biomaterial really is, what the frequently used term biocompatibility stands for, and why it is so important for biomaterials to be biocompatible. It then:

• Examines the structural, chemical, macromechanical, micro/nanomechanical, and tribological properties and residual stress of HAp coatings


• Evaluates the efficacies under simulated body fluid immersion for MAPS- and MIPS-HAp coatings developed on biomedical implant-grade SS316L substrates


• Offers a comprehensive survey of state-of-the-art in vivo studies of MIPS-HAp coatings, presenting the results of pioneering research related to bone defect fixation

Shedding light on the future scope and possibilities of MIPS-HAp coatings, Microplasma Sprayed Hydroxyapatite Coatings provides a valuable reference for students, researchers, and practitioners of biomedical engineering and materials science.

"This unique book on development of microplasma sprayed HAp coating has been organized in a very compact yet comprehensive manner. This book also highlights the horizons of future research that invites the attention of global community, particularly those in bio-medical materials and bio-medical engineering field. This book will surely act as a very useful reference material for both graduate/post-graduate students and researchers in the field of biomedical, orthopedic and manufacturing engineering and research. I truly believ that this is the first ever effort which covers almost all the broad subject area of "HAp coatings developed by microplasma spraying including those of the more commercially accepted plasma spraying method" for developing HAp coated implants and prosthesis."
—Bikramjit Basu, Professor, Materials Research Center, Indian Institute of Science, Bangalore, Associate Faculty, Interdisciplinary Bio-Engineering Program, IISc, Bangalore, Adjunct Professor, Indian Institute of Technology Kanpur, India

"The organization of topics is done very methodically covering all the related and even peripheral issues. The subject is covered well with thorough details and critical views. The book would be a good reference point for researchers working on HA based coatings for orthopedic application."
—Debrupa Lahiri, IIT Roorkee, India

"The lucid presentation style makes it easy for the new entrant to be gradually initiated into the field without any shock or jerk. What is most striking and appealing about the book is that even after starting from basic simple premises it has very capably provided vast and in-depth discussion to an extent that would be very lucrative for advanced researchers from both Govt. and private research organizations in the emerging field of biomedical applications of ceramic coatings."
—Dr. Satyam Priyadarshy, Founder, Reignite strategy
