本文介绍并评价了一种测定薄硬涂层杨氏模量的拉伸试验方法。当施加到PVD TiN和NbN涂层上的不锈钢箔，通过力-应变图获得的弹性模量范围为380和425 GPa之间的TiN涂层，并为350 GPa的单一NbN涂层测试。它的结论是，该方法是易于执行，并允许可靠的测定薄硬涂层的杨氏模量，它可以应用于几乎任何种类的涂层上广泛的基材材料。
The present paper describes and evaluates a tensile testing method for determination of the Young's modulus of thin hard coatings. When applied to PVD TiN and NbN coatings on stainless steel foils, the elastic modulus obtained through force—strain plots ranged between 380 and 425 GPa for TiN coatings, and was 350 GPa for the single NbN coating tested. It is concluded that the method is easy to perform and allows reliable determination of the Young's modulus of thin hard coatings, and that it can be applied to almost any kind of coating on a wide range of substrate materials.
