摘要

对基体材料镉镍铁合金600和多层TiAlN/TiN涂层的激光表面改性在基础研究和实际应用中有着很好的前景。本文观察了由超短脉冲(fs和ns)和短脉冲(ns)激光器引起的镉镍铁合金600和TiAlN/TiN镀层的表面变化。结果显示

3种激光都能使靶面发生形态改变

超短脉冲的破坏轮廓更为清晰。与ps激光脉冲相比

fs激光脉冲能产生更严重的破坏。与产生半球体形状的ps激光束相反

fs激光脉冲产生的破坏斑是圆锥形的。另外

ns脉冲辐照时热效应占支配地位

且所有的辐照都伴随着等离子体。

Abstract

The laser surface modifications of a bulk material Inconel 600 and a multilayered titanium-aluminium-nitride/titanium-nitride(TiAlN/TiN) coating are of great interest for fundamental and practical aspects. Observation of surface changes of the Inconel 600 and TiAlN/TiN induced by ultra-short (fs and ps) and short (ns) lasers is considered. It is shown that all laser systems can stimulate morphological changes at the target surface

and the irradiation with ultra-short pulses results in a better definition of the damage. Fs laser pulses can produce a sharper destruction in comparison to the ps pulses and it gives the conical cross section of the crater

which is in contrast to the semispherical shapes ps laser beams. Furthermore

thermal effects are dominant in the case of ns pulse

and all irradiations are accompanied by the plasma.
