Abstract
The present application relates to the technical field of laser cladding, and provides a device and method for ultrasonic-assisted laser cladding of bioactive coatings. The device includes: an ultrasonic generator, a cladding laser and a reaction cylinder; one end of the reaction cylinder is provided with a transparent plate, The cladding laser is arranged above the transparent plate, the horn is arranged in the reaction cylinder, the end of the horn close to the transparent plate is provided with a clamp, the end of the horn away from the transparent plate is arranged with a transducer, and the ultrasonic generator is arranged in the The outer side of the reaction cylinder is connected with the transducer, the part to be clad is placed on the fixture, the cladding laser, ultrasonic generator and transducer work synchronously to make the laser beam and ultrasonic act synchronously on the surface of the part to be clad to form biological Active coating. The bioactive coating utilizes the cavitation effect, mechanical effect and thermal effect of ultrasonic vibration, so that the coating has good performance, high hardness, good wear resistance and good biological activity.
Description
technical field [0001] The present application belongs to the technical field of laser cladding, and more particularly relates to a device and method for ultrasonic-assisted laser cladding of biologically active coatings. Background technique [0002] Biomaterials include metal materials and ceramic materials. Among them, metal materials have the advantages of high compressive and tensile strength, good impact resistance and ductility, good formability and high reliability. Bioceramic materials, as inorganic biomedical materials, have excellent biocompatibility and bioactivity. [0003] As a metal implant, titanium alloy has become the preferred material due to its good biocompatibility, excellent biomechanical properties and excellent forming and manufacturing ability. However, the wear resistance of titanium alloys is poor. In the fretting environment in the body, wear debris will be generated and metal ions will be released. The wear debris will lead to poor bone resorp...
