ABSTRACT

Metal cutting is a necessary operation in any production industry. Rapid production has become a necessity as a result of recent trends in high-speed machining and automation. The demand for more sophisticated and advanced cutting tools has significantly increased in recent years. The properties of alloy metals can be improved by applying a thin film to enhance or reduce specific properties based on product needs. The effect is being able to operate the tool at a higher cutting speed, feed rate, depth of cut, and longer tool life, with a dry machining possibility for the end-user when cutting tools are appropriately coated and performing as intended using thin films. Thin coatings improve cutting tool wear resistance, oxidation resistance, friction reduction, resistance to metal fatigue, as well as thermal shock resistance. On the other hand, thin film morphology and stability are crucial challenges in cutting tool applications as thin film morphology is heavily dependent on deposition techniques. As a result, based on the available studies, this article presents a critical review of deposition coating techniques, characterisation methods, and evaluation techniques in order to prevent excessive damage and improve the mechanical properties of cutting tools. The anticipated outcomes of this review can be used as a guide to help researchers understand various coating techniques and their effects on cutting tool properties.

摘要

金属切削是任何生产行业的必要工序。由于高速加工和自动化的最新趋势，快速生产已成为必然。近年来，对更复杂、更先进切削刀具的需求显着增加。合金金属的性能可以通过应用薄膜来根据产品需求增强或降低特定性能来改善。其效果是能够以更高的切削速度、进给率、切削深度和更长的刀具寿命来操作刀具，并且当切削刀具使用薄膜进行适当涂层并按预期执行时，最终用户可以进行干加工。薄涂层可提高切削刀具的耐磨性、抗氧化性、减少摩擦性、抗金属疲劳性以及抗热震性。另一方面，薄膜形态和稳定性是切削刀具应用中的关键挑战，因为薄膜形态严重依赖于沉积技术。因此，基于现有的研究，本文对沉积涂层技术、表征方法和评估技术进行了严格的审查，以防止过度损坏并提高切削刀具的机械性能。本次综述的预期结果可以作为指南，帮助研究人员了解各种涂层技术及其对切削刀具性能的影响。表征方法和评估技术，以防止过度损坏并提高切削刀具的机械性能。本次综述的预期结果可以作为指南，帮助研究人员了解各种涂层技术及其对切削刀具性能的影响。表征方法和评估技术，以防止过度损坏并提高切削刀具的机械性能。本次综述的预期结果可以作为指南，帮助研究人员了解各种涂层技术及其对切削刀具性能的影响。
