Laser Cladding Repair Technology for Cylinder Bore Inner Hole

Laser cladding repair processing for cylinder bore inner holes is a high-precision, high-efficiency advanced repair technology widely used for the restoration of cylinder bore inner holes in various mechanical equipment. This technology rapidly heats and melts the cladding material using a laser beam, forming a metallurgical bond with the base material to achieve precise repair of damage in the cylinder bore inner hole.

I. Principle of Laser Cladding Repair Technology for Cylinder Bore Inner Holes

Laser cladding repair processing for cylinder bore inner holes primarily utilizes the high energy density and precise controllability of the laser beam to spray the cladding material in fine particle form onto the surface of the cylinder bore inner hole. The laser beam rapidly heats the cladding material to a molten state while forming a thin molten pool on the surface of the base material. Under the continuous action of the laser beam, the cladding material in the molten pool undergoes a metallurgical reaction with the base material, forming a strong metallurgical bonding layer. After the molten pool cools and solidifies, the damage to the cylinder bore inner hole is effectively repaired.
