Abstract: The disclosure provides biocompatible metal compositions, methods of making such compositions and uses thereof, including a method of synthesizing zeolite coatings. The disclosure further provides the zeolite-hydroxyapatite composite coatings and methods of making them, which includes forming a base zeolite layer, forming a hydroxyapatite layer on the base zeolite layer, and interlocking the hydroxyapatite layer with an outer zeolite layer. The composite can be formed on a metal substrate for bioimplants, such as titanium alloy and/or stainless steel, which is used for bioimplants.
