热喷涂涂层和摩擦表面是许多工业部门的关注点。它们用于提高轻质材料的耐磨性或用于表面的保油。轻质材料通常用于汽车行业，作为发动机缸体生产中的减重解决方案。为此，有必要对气缸套进行涂层以确保耐磨性。在大多数情况下，涂层直接喷涂到表面上。以前的研究表明，可以将这些涂层反向转移到其他表面上[1]。这是通过将等离子喷涂涂层移植到压力铸造表面上来实现的。与直接涂覆的表面相比，这些移植的表面表现出更好的粘合强度、更光滑的表面和更低的形状偏差。此外，它表明，甚至微观结构的表面涂层等离子喷涂可以转移到压力铸造表面。本文介绍了不同的微结构转移到压力铸造表面的热喷涂涂层的发展和微铣削。在开发过程中，设计了具有不同形状和纵横比以及薄摩擦表面的微结构，以评估移植过程的优点和局限性。在随后的实验中，微铣削过程和模拟的涂层移植和分析。
Thermally sprayed coatings and tribological surfaces are a point of interest in many industrial sectors. They are used for better wear resistance of lightweight materials or for oil retention on surfaces. Lightweight materials are often used in the automotive industry as a weight-saving solution in the production of engine blocks. For this, it is necessary to coat the cylinder liners to ensure wear resistance. In most cases, the coating is sprayed directly onto the surface. Previous research has shown that it is possible to transfer these coatings inversely onto other surfaces [1]. This was achieved with plasma sprayed coatings which were transplanted onto pressure-casted surfaces. These transplanted surfaces exhibited better adhesive strength, smoother surfaces, and lower form deviation compared to directly coated surfaces. Additionally, it was shown that even microstructures of a surface coated by plasma spraying can be transferred to pressure-casted surfaces. This paper presents the development and micromilling of different microstructures for transferring thermally sprayed coatings onto pressure-casted surfaces. In the development process, microstructures with different shapes and aspect ratios as well as thin tribological surfaces are designed in order to evaluate the advantages and limitations of the transplantation process. In subsequent experiments, the micromilling process and a simulation of the coating transplantation are presented and analyzed.
