摘要

6061铝合金在工业热交换器,散热器,化学设备以及飞机和船舶的框架中具有广泛的应用。其物理和机械性能,如轻质,高强度,耐腐蚀性,导热性和导电性,使其成为这些应用的合适材料选择。在热和微机电应用中,例如用于微电子的热交换器、散热器和散热器,热量的消散起着重要的作用。为了达到最佳的散热效果,需要更大的表面积。这可以通过制造微通道来修饰表面来实现。许多加工技术被用于在不同的材料上制造微通道。激光是一种灵活的非接触加工工具,可用于在几乎任何材料上创建任何轮廓或轮廓。近年来,由于激光技术的进步,使用超快激光材料加工是进一步扩展高质量微通道制造的潜在途径,没有热影响区引起的缺陷,并且以可持续的方式。本文介绍了利用低功率(<4 W) 400 fs激光系统在6061铝合金表面制备微通道的实验工作。利用扫描电子显微镜和三维轮廓术对制备的微通道的尺寸精度进行了评估。此外,由于加工速度和规模在工业激光加工中很重要,因此研究了使用扫描光学作为开发快速和可扩展的超快激光工艺的手段。

Ultrafast Laser Fabrication of Microchannels on Aluminium Alloy Substrate
Aluminium alloy 6061 has a versatile application within industrial heat exchangers, heat sinks, chemical equipment, and frames of aircraft and ships. Its physical and mechanical properties such as lightweight, high strength, corrosion resistance, and thermal and electrical conductivity make it a suitable material choice for these applications. Within thermal and micro-electromechanical applications, such as heat exchanges, radiators, and heat sinks used in microelectronics, the dissipation of heat plays an important role. For optimum heat dissipation, a higher surface area is required. This can be achieved by modifying the surface by fabricating microchannels. A number of processing techniques are used for fabricating microchannels on different materials. A laser is a flexible non-contact machining tool that may be used to create any profile or contour on practically any material. In recent times due to the advancement in laser technology, the use of ultrafast laser material processing is one potential route toward further extending the fabrication of high-quality microchannels without defects caused due to heat-affected zones and in a sustainable manner. In this paper, we present an experimental work of fabrication of microchannels on an aluminium alloy 6061 surfaces by using a low power (<4 W) 400 fs laser system. The dimensional accuracy of the fabricated microchannels is assessed using scanning electron microscopy and 3D profilometry. Furthermore, as processing speed and scale is of importance in industrial laser processes, the use of scanning optics is examined as a means of developing a rapid and scalable ultrafast laser process.
