The purpose of this study was to evaluate the possibility of using mechanical spectroscopy to determine the strength of tool coatings from their lifespan. Mechanical spectroscopy with the determination of the index tan\(\delta \) (internal friction) was used as the research method. Samples were coated with lamellae composed of WC-6wt% Co cemented carbides. The specimens measured 1.0 mm, 3.0 mm, and 40.0 mm, created using a conventional industrial liquid phase sintering procedure. The original powder consisted of cobalt with traces of chromium and vanadium, and submicron WC grains. The tools tested included carbide cutting tools, and the workpieces were steel alloys. Comparative results showed that coated tools had significantly improved tool life and durability. The relationship between the coating and tool life was evident, providing a practical approach for predictive and non-destructive analyses of coatings on tool durability for composite and finely structured materials.

本研究的目的是评估使用机械光谱法根据工具涂层的使用寿命确定其强度的可能性。采用机械光谱法测定指数 tan\(\delta \)（内摩擦）作为研究方法。样品涂有由 WC-6wt% Co 硬质合金组成的薄片。样品尺寸为 1.0 毫米、3.0 毫米和 40.0 毫米，采用传统工业液相烧结程序制成。原始粉末由钴、微量铬和钒以及亚微米 WC 颗粒组成。测试的刀具包括硬质合金切削刀具，工件为钢合金。比较结果表明，涂​​层刀具显着提高了刀具寿命和耐用性。涂层和刀具寿命之间的关系很明显，为复合材料和精细结构材料的刀具耐用性涂层的预测和无损分析提供了实用的方法。
