The present application relates to a kind of full amorphous no crack iron-based amorphous
coating of ultra-high speed
laser cladding and preparation method.To be cladded workpiece is preheated, and the workpiece to be cladded that is preheated is clamped with chuck, and is placed on rotating carrier;Adjust the
powder feeding speed of cladding device, carrier gas flow,
shielding gas flow;Adjust the distance between cladding head and the workpiece to be cladded,
laser focal point,
powder flow focal point, set the
moving speed of cladding head;Rotating carrier drives the workpiece to be cladded to rotate, and from outside to inside,
laser cladding is started, and the full amorphous no crack iron-based amorphous
coating of ultra-high speed laser cladding is formed on the surface of the workpiece to be cladded.The present application controls the process parameters of ultra-high speed laser cladding, and selects the parameters suitable for
processing amorphous
coating, realizes the rapid cooling of coating and defect-free preparation while ensuring the complete amorphous of coating.The coating has high
corrosion resistance and excellent mechanical properties.
