The present invention describes equipment and a method that are capable of carrying out the coating of metallic material on particulate materials through cathodic spraying (sputtering). The main advantages of the invention are sterile and semi-continuous production, precision in the thickness of the covered coat, as well as the reduction of occupational costs, since it is a semi-automated process.The present invention is especially for application in the manufacture of raw materials to be used in the medical field.
