Impact tests of different frequencies can be applied to simulate the cyclic fatigue load of the tool under different working conditions as well as different impact frequencies. The main objective of the present article is to review different impact test methods for hard tool coatings. In this regard, impact tests are divided into three categories, including high-frequency, medium-frequency, and low-frequency tests. In terms of the impact scale, impact tests can be divided into micro-scale and nano-scale tests. The impact tests at micro-scales and nano-scales aim to characterize the coating substrate and the coating itself, respectively. It is found that the interface properties between the coating and the substrate have a remarkable impact on the fatigue resistance of the tool coating. Finally, the design and future development of the impact test are discussed.

切削工具硬质涂层的机械冲击试验方法:综述

可以应用不同频率的冲击测试来模拟工具在不同工作条件以及不同冲击频率下的周期性疲劳载荷。本文的主要目的是回顾硬质工具涂层的不同冲击测试方法。在这方面,冲击测试分为三类,包括高频,中频和低频测试。就冲击规模而言,冲击试验可分为微观试验和纳米试验。微观和纳米级的冲击试验旨在分别表征涂层基材和涂层本身。发现涂层与基底之间的界面性质对工具涂层的抗疲劳性具有显着影响。最后,
