Hydroxyapatite Coating on Alloys CoCrMo-TiN with Sol-Gel Method
Hydroxyapatite is synthesized by precipitation-sonification using calcium from field snail shell and powder phosphorus from (NH4)2HPO4. The calcium value was measured by atomic absorption spectrophotometer was 82.82%.The temperatures were varied on 600, 800, and 1000 oC to determine the best tempera...
