specific Embodiment 1

[0026] Specific embodiment 1: the workpiece is pure titanium, and the surface of pure titanium is polished and cleaned with acetone and alcohol; 300-mesh stainless steel square mesh is bonded to the surface of pure titanium through an organic adhesive; an aluminum foil with a thickness of 240 μm is covered on the The surface of the stainless steel square mesh; the water film with a thickness of about 1mm will be covered on the surface of the aluminum foil; the repetition frequency of the laser used in the present invention is 5HZ, and the laser emits energy of 12.5J and pulsed laser with a pulse width of 10ns. After focusing through the focusing lens, An irradiation area with a diameter of about 4.5cm is formed on the surface of the aluminum foil. The aluminum foil absorbs the laser energy and explodes to form a high-intensity shock wave. Under the strong thrust generated by the shock wave, the lower end of the 300-mesh stainless steel square mesh is embedded in the pure titaniu...

Abstract

The invention provides high efficiency apparatus and method based on laser shock wave for manufacturing micro grooves.The shock wave is generated by an absorbed layer in high energy pulse laser irradiation. The shock wave induced by the laser generates huge pressure, a metal mesh is embedded in a metal material by utilizing the pressure and a micro groove is formed on a surface of the metal material.

Description

technical field [0001] The invention relates to the field of micro-manufacturing on the surface of metal materials, in particular to a high-efficiency micro-groove manufacturing technology based on laser shock waves. Background technique [0002] Making micron-scale microgrooves on the surface of ships and underwater vehicles is an effective way to reduce navigation resistance; making micron-scale microgrooves on the surface of friction pairs can be used to store lubricating oil and wear during friction Fragments greatly improve the wear resistance of the friction pair; at the same time, the fabrication of micro-grooves is also one of the important research directions in the fields of micro-electromechanical systems (MEMS) and biotechnology. [0003] At present, the techniques for preparing microgrooves on metal surfaces mainly include mechanical methods, electrochemical methods, laser ablation methods, and electron beam processing methods. The mechanical method has the dis...
