Calcium phosphate coatings: a comparative study between simultaneous vapor deposition and electron beam deposition techniques

A comparative study on calcium phosphate coatings produced by two different physical vapor deposition techniques namely, simultaneous vapor deposition (SVD) and electron beam deposition (EBD), has been carried out. All the as-deposited films were annealed at various temperature levels to achieve cry...
