    • A method and system for improving the capability of a surface (14) of an organic structure (16) to bond with another material includes irradiating a target area of the surface of a structure with pulsed, incoherent optical energy (18) from an optical energy source (12) having wavelength components which range from 170-5000 nanometers at an intensity sufficient to photodecompose any adventitious organic substances on the surface and to photodecompose a thin layer of molecular bonds forming the surface of the structure; and exposing the target area of the surface (14) to an ionized gas stream (24) from an ionized gas generator (26) that chemically reacts with the target area of the surface to increase the surface free energy of the surface. A similar method may also be employed to improve the bondability of a metal surface by impinging a target area on a metal surface with a stream of particles (36) to preclean and dislodge any inorganic substances from the surface; and then irradiating the target area of the surface with pulsed, incoherent optical energy (18) having wavelength components in the range of 170-5000 nanometers at an intensity sufficient to photodecompose any remaining organic substances present on the surface.
    • 一种提高的有机结构(16)的一个表面(14)与另一种材料结合的能力的方法和系统包括:从在光能量照射脉冲,非相干光的能量(18)的结构的表面的目标区域 源(12),其具有波长分量从170至5000纳米米范围处强度足够的光分解到表面上的任何外来的有机物质和光分解的形成结构的表面的分子键的薄层; 并与该表面的目标区域,以增加该表面的表面自由能的表面(14)的目标区域暴露于从其在电离气体发生器(26)电离气体流(24)并进行化学反应。 因此可以采用类似的方法通过用颗粒(36)的流预清洁和逐出表面的任何无机物在金属表面上撞击的目标区域,以改善金属表面的粘结能力; 然后照射脉冲,非相干光能量具有在强度足够的光分解,以在表面上存在的任何残留的有机物质在170至5000纳米米的范围内的波长成分的表面的目标区域(18)。
