Newton Fund - LASTEC-Laser surface texturing of compressor’s mechanical components: Increasing energy efficiency by improved tribological performance

项目lasstec（压缩机机械部件的激光表面纹理：通过改善摩擦学性能提高能源效率）涉及创新和优化先进的激光制造工艺，旨在降低制冷系统的功耗。该项目与SENAI-SESI / Innovate UK竞赛的“能源”主题保持一致，更具体地说，是“优化制造过程以降低功耗”的主题。因此，该项目旨在开发一种干燥、无溶剂、环保的一步工艺，对压缩机的机械部件使用灵活高效的激光表面纹理。这将大大提高压缩机的能源效率，降低其耗电量，并延长巴西和世界上无数家用和商用制冷系统的使用寿命。基于激光的工艺有望通过创建能够降低压缩机配合面和往复面之间摩擦系数（摩擦力）的纹理来改善机械部件的摩擦学性能。为了开发该项目，全球领先的密封压缩机制造商恩布拉科将与SENAI创新研究所（ISI-Laser， ISI-SM和ISI-Eng）合作。Superfícies)以及牛津激光有限公司，一家拥有40年历史的英国公司，致力于为先进制造和研发活动设计和制造定制交钥匙激光微加工系统。

Project LASTEC (Laser Surface Texturing of Compressor’s Mechanical Components: Increasing Energy Efficiency by Improved TribologicalPerformance) involves innovation and optimisation of an advanced laser-based manufacturing process aimed at diminishing powerconsumption on refrigeration systems. The project is aligned with the “Energy” theme of the SENAI-SESI / Innovate UK competition,more specifically, with the topic “optimization of manufacturing processes to diminish power consumption”. Thus, the project aims atdeveloping a dry, solvent free environmentally friendly, one-step process, using flexible and efficient laser surface texturing forcompressor’s mechanical components. This will increase significantly the compressor energy efficiency, reduce its power consumptionand extend its lifespan for countless household and commercial refrigeration systems in Brazil and in the world. The laser-based processis expected to improve the tribological performance of the mechanical components by creating textures capable of reducing the frictioncoefficient (friction forces) between the compressor’s mating and reciprocating surfaces. To develop the project, EMBRACO, the globalleader in manufacturing of hermetic compressors, will join forces with the SENAI Innovation Institutes (ISI-Laser, ISI-SM and ISI-Eng.Superfícies) as well as Oxford Lasers Ltd, a 40 years old UK based company working on the design and manufacture of custom turnkeylaser micromachining systems for advanced manufacturing and R&D activities.
