A Research on Optical Fiber Laser Interaction with Materials, Applied on Surface Cleaning of Mechanical Parts

Currently in Vietnam, the mechanical cleaning methods are mainly traditional ones such as shot blasting, sand blasting, manual cleaning, or cleaning with chemical compounds, to name a few. Shot blasting and sand blasting have low productivity, they can cause damage as well as deformation to surface and are ineffective with small details whose the oxide layer has high mechanical durability. Manual cleaning by hand has low productivity, uneven cleaning quality. Chemical methods produce a lot of toxic waste which affects the environment. Laser cleaning technology can overcome these disadvantages and is fully suitable for Vietnamese conditions. The objective of the paper is to study the interaction of materials with lasers, applied in the design of metal oxide cleaning systems of mechanical parts. The results showed that the ability to clean iron oxide with peel thickness of up to 68µm and the relationship between the thickness of the stripped layer of rust and steel substrate capacity
