Description
MICRO-PART SURFACE MODIFICATION DEVICE
TECHNICAL FIELD
The present disclosure relates to the field of material surface modification, and in particular, to a micro-part surface modification device.
BACKGROUND
Micro mechanical products have broad application prospects in the fields of biomedicine, aerospace, national defense, high-tech electronic products, and so on. Metal micro-parts in the micro mechanical products, such as micro gears and micro switches serving as main load-bearing parts, are usually affected by cyclic loading resulting from heat and force, which easily causes wear and fatigue damage and lead to product failure. The development of micro mechanical products raises higher requirements on the surface quality, wear resistance and fatigue resistance of micro structural parts. In addition, micro-parts used in medicine often require surface treatment such as cleaning, frosted finish, matte finish, enhanced adhesion, deburring, or texturing.
The methods of severe plastic deformation of metal surfaces can achieve material surface modification without introducing other elements, and the interface between the modified layer and the matrix has a uniform transition without defects such as pores arid contamination. The methods of surface severe plastic deformation mainly include shot peening, sand blasting, and surface ultrasonic grinding. In the above methods, large-sized shots are usually used to impact the material surfaces, arid the shots are too large to be suitable for surface modification of micro-parts. Laser shock peening, also known as laser peening, is to modify material surface with a high-energy nanosecond pulse laser-induced shock wave, thereby producing compressive residual stress and microstructure refinement to improve the service performance of the material. The laser shock peening generally adopts spot diameters in millimeters and the single pulse energy is large. The laser shock peening with small spots cannot use a protective coating and causes certain thermal effects, making it unsuitable for surface modification of micro-parts. The prior art discloses a surface strengthening device based on laser-driven micro-particle impact, where a polydimethylsiloxane (PDMS) membrane driven by laser-induced plasma pushes small particles to impact a target at high speed, causing plastic deformation of the target surface to achieve surface strengthening. However, severe plastic deformation strengthening requires cumulative plastic deformation on the metal surfaces, and the previously developed method cannot achieve dense strengthened layers.
