摘要

该工作涉及研究分析在热模锻过程中，通过使用具有低摩擦系数的多层TiC/C涂层的ALWIN （CrAlSiN）涂层来增加用于生产汽车工业锻件（由AISI304钢制成）的锻模的耐久性的可能性。通过对5套锻件的工业过程运行试验，对提高锻件使用寿命的应用方法进行了评价。该研究比较了ALWIN XC涂层（基材层为CrN，而不是标准扩散氮化层）和标准工具（没有额外涂层）的结果。作为工作的一部分，进行了一些测试，包括宏观和微观测试、数值模拟和硬度测量。详细的测试表明，使用ALWIN XC涂层可以提高锻造工具的耐久性，这在5套锻造工具中得到了证实。与单独使用氮化层相比，对于这些锻造工具（锻造相同的不锈钢锻造），使用氮化并没有带来积极的效果。这再次证实了每个产品，每个锻造工艺都需要一个单独的方法，因为工艺上的微小变化会对锻造工具的使用寿命产生积极或消极的影响。

Analysis of the possibilities of increasing the durability of forging tools used in the production of forgings for the automotive industry by applying the ALWIN XC hard coating

The work concerns research on the analysis of the possibility of increasing the durability of forging dies used for the production of forgings (made of AISI304 steel) for the automotive industry during the hot die forging process by using the ALWIN (CrAlSiN) coating with a multi-layer TiC/C coating with a low coefficient of friction. The assessment of the applied method of increasing the service life of tools was carried out based on operational tests during the industrial process for 5 sets of forging tools. The work compared the results for the tool with the ALWIN XC coating (where the base layer is CrN, not the standard diffusion nitrided layer) and for standard tools (without additional coatings). As part of the work, a number of tests were carried out, including macroscopic and microscopic tests, numerical simulations, and hardness measurements. The detailed tests showed that the use of the ALWIN XC coating allows for increasing the durability of forging tools, which was confirmed for 5 sets of forging tools. In contrast to the nitrided layer used alone, for these forging tools (forging the same stainless steel forging), the use of nitriding did not bring positive results. This confirms once again that each product, each forging process requires an individual approach, because small changes in the process can have a positive or negative effect on the service life of the forging tools.

期刊介绍： The International Journal of Refractory Metals and Hard Materials (IJRMHM) publishes original research articles concerned with all aspects of refractory metals and hard materials. Refractory metals are defined as metals with melting points higher than 1800 °C. These are tungsten, molybdenum, chromium, tantalum, niobium, hafnium, and rhenium, as well as many compounds and alloys based thereupon. Hard materials that are included in the scope of this journal are defined as materials with hardness values higher than 1000 kg/mm2, primarily intended for applications as manufacturing tools or wear resistant components in mechanical systems. Thus they encompass carbides, nitrides and borides of metals, and related compounds. A special focus of this journal is put on the family of hardmetals, which is also known as cemented tungsten carbide, and cermets which are based on titanium carbide and carbonitrides with or without a metal binder. Ceramics and superhard materials including diamond and cubic boron nitride may also be accepted provided the subject material is presented as hard materials as defined above.
