Preparation of the Intermediate Layers on CoNiCrMo‐Alloys Using Alkaline Treatment for Improving the Bonding of Bioceramic Coating
Source abstract
Abstract
Can alkaline pretreatment improve the bond between metallic implants and hydroxyapatite bioceramic coatings? Very much so, but it affords proper choice of the base. Treatment with 10 M NaOH did not result in a crystalline coating on CoNiCrMo whereas saturated Ca(OH)2 solution produces a stable, homogeneous coating of Ca2Co2O5 as a bridge compound. The Figure shows two examples of metallic knee prosthesis parts made of CoNiCrMo and CoCrMo, resp. for use in such implants.
