Method of providing a desired material on at least a portion of a surface of a substrate of a component, such as a medical implant component. The method may comprise the steps of arranging the component in a holding fixture which is capable of holding the component at atmospheric or substantially atmospheric pressure, and spraying particles of the desired material at a predetermined high velocity toward the at least one portion of the surface of the substrate so as to enable a layer of the material to be accumulated thereon. The spraying may be performed at atmospheric or substantially atmospheric pressure. The desired material may be a reactive type material, such as titanium or an alloy thereof. The method may enable a high density coating or layer of the material to be provided without the use of a post spray thermal consolidation process.
