Effect of the processing parameters on the integrity of calcium phosphate coatings produced by RF-magnetron sputtering

Calcium phosphate (CaP) compounds like hydroxyapatite and tricalcium phosphates are considered to be very important biomaterials. This study used RF-magnetron sputtering (RF-MS) to deposit CaP onto 316L SS. Due to the complex nature of the effect of different sputtering parameters on the quality and...
