研究目的
Optimizing pulsed laser ablation on stainless steel for improving corrosion resistance by Taguchi method.
研究成果
The study successfully optimized laser parameters for improving the corrosion resistance of stainless steel using the Taguchi method. The power of laser irradiation was identified as the most significant parameter affecting corrosion resistance in neutral solution, while overlap rate was most influential in acidic solution. The optimized parameters were validated experimentally, showing improved corrosion resistance.
研究不足
The study is limited to the optimization of laser parameters for corrosion resistance of stainless steel in specific solutions (3.5 wt.% NaCl and 10% HCl). The effectiveness of the optimized parameters in other corrosive environments or on different materials was not explored.
