Chromium-plated cobalt-based metal oxide ceramic coating for medical apparatus and instruments

The invention discloses a chromium-plated cobalt-based metal oxide ceramic coating for medical equipment, the ceramic coating comprises a matrix layer, an outer layer of the matrix layer is immersed in a regulator for immersion treatment to form an immersion layer, and the immersion layer is also provided with a chromium-cobalt-based metal layer; the chromium-cobalt-based metal layer, the immersion layer and the matrix layer are sequentially arranged from top to bottom; and the thicknesses of the chromium-cobalt-based metal layer, the immersion layer and the matrix layer are respectively 2-3 microns, 1-3 microns and 4-5 microns. According to the metal oxide ceramic coating, the matrix layer is matched with the conditioning agent for immersion treatment, then through coordination of the chromium-cobalt-based metal layer, mutual regulation and effect regulation of layer structures, mutual coordination of hydroxyapatite and nano silicon dioxide as the conditioning agent, and specific improvement of the process,
