摘要

高功率二极管激光(HPDL)表面处理有可能改变两段瓷砖灌浆的润湿性。这种变化表现为接触角的减小，这是由于HPDL诱导的变化降低了表面粗糙度，增加了表面o2含量，增加了表面能的极性成分。此外，发现HPDL处理两段瓷砖浆液表面通过增加粘接功来改善粘接特性。结合选定液体金属的润湿性实验，采用电子方法对两段瓷砖灌浆在HPDL前后的粘结特性进行了分析。认为HPDL引起的两段瓷砖浆液的变化产生了带隙能量降低的表面，从而通过增加金属氧化物处的电子转移而增加了wad。

An analysis of the bonding mechanisms active in a high power diode laser generated two-stage ceramic tile grout

It is quite possible to bring about changes in the wettability characteristics of a two-stage ceramic tile grout by means of high power diode laser (HPDL) surface treatment. Such changes manifest themselves as a reduction in the contact angle, , and are due to the HPDL inducing changes which reduce the surface roughness, increase the surface O 2 content and increasing the polar component of the surface energy. What is more, HPDL treatment of the two-stage ceramic tile grout surface was found to effect an improvement in the bonding characteristics by increasing the work of adhesion, W ad . Along with wettability experiments carried out with selected liquid-metals, an electronic approach was used to identify the bonding characteristics of the two-stage ceramic tile grout before and after HPDL. It is thought that HPDL induced changes to the two-stage ceramic tile grout produced a surface with a reduced bandgap energy which consequently increased W ad by increasing the electron transfer at the metal-oxide i...

期刊介绍： Lasers in Engineering publishes original (primary) research articles, reviews, short communications and letters on all aspects relating to the application of lasers in the many different branches of engineering and related disciplines. The topics covered by Lasers in Engineering are the use of lasers: in sensors or measuring and for mapping devices; in electrocomponent fabrication; for materials processing; as integral parts of production assemblies; within the fields of biotechnology and bioengineering; in micro- and nanofabrication; as well as the materials and processing aspects of techniques such as cutting, drilling, marking, cladding, additive manufacturing (AM), alloying, welding and surface treatment and engineering. Lasers in Engineering presents a balanced account of future developments, fundamental aspects and industrial innovations driven by the deployment of lasers. Modern technology has a vitally important role to play in meeting the increasingly stringent demands made on material and production systems. Lasers in Engineering provides a readily accessible medium for the rapid reporting of new knowledge, and technological and scientific advances in these areas.
