“…The diamond abrasive grains have a grit size of D 76. valleys in cross-grid pattern and flat areas or plateaus without profile peaks [6][7][8][9]. The tool and the process parameters, causing different material removal mechanisms, influence the resulting surface characteristics roughness and bearing area ratio [6,7,10,11]. When considering previous models the material removal mechanisms in microfinishing processes can be assumed as an interaction of the tribological wear mechanisms microcracking, microfatigue, and the mechanisms microridging, microploughing, and microcutting in analogy to longitudinal stroke honing processes [5,[12][13][14][15].…”

Microfinishing, also known as superfinishing or short-stroke honing, is a commonly used process for generating technical surfaces focusing on tribological applications. Due to microfinishing processes high surface qualities are manufacturable regarding the surface roughness and bearing area ratio. While the required characteristics for tribological loaded workpieces are changing with their rising significance, the surface structuring is becoming more and more important. With the use of defined abrasive belts, the possibilities of surface structuring by microfinishing are enhanced. The possibilities and challenges concerning surface structuring by microfinishing applying defined abrasive belts are described in this research study. Therefore, a geometrical-kinematic simulation is used to predict the theoretical structures generated by microfinishing, while in experimental investigations the influences of kinematic parameters and a multi-stage process sequence are considered.

“…There are several grinding materials that can be utilized as abrasives, however, the two most commonly used grain types found in sandpaper consist of aluminum oxide (Al 2 O 3 ) or silicon carbide (SiC) [6][7][8]. Variations in the material morphology and the surface structure will have a large impact on the performance and the wear dynamics of the abrasive, which has also previously been demonstrated [8,9]. Results from these published studies suggest that for example the grain size of the abrasives has a large effect on the wear rate, with a diminished wear rate below a certain particle diameter.…”

Coated abrasives (sandpaper) are imperative in various industrial areas, including the automotive and the metal industry. An exact outcome is often highly appreciated in abrasion processes, which means that the wear process must be precisely controlled. In this paper, a new method for analyzing the grinding process of coated abrasives is proposed. In order to study the grinding properties of sandpaper, a tribology cell was connected to a rheometer. The experiments consisted of unlubricated (dry) steel balls-on-disc experiments on coated abrasive with aluminum oxide grains. The friction and wear data showed that the rheometer equipped with a tribology cell can be used to measure different tribological parameters, such as the friction coefficient and the Gap. The wear process was investigated over a range of abrasive grain sizes (9–40 µm) and a variety of different loads (1–10 N). Results from these experiments showed that the abrasive wear increased with increasing particle size and normal load. Hence, it is proposed that this method is a reliable approach for investigating the wear process of coated abrasives.

“…In addition, these surfaces have a high bearing area ratio. The material removal mechanisms that influence the roughness and bearing surface ratio are determined by the tool specifications, process parameters, and workpiece properties [2,7,27,28]. The material removal mechanisms in microfinishing processes can be assumed as an interaction of mechanisms like microcracking and microfatigue, and mechanisms of microridging, microploughing, and microcutting, analogous to longitudinal stroke honing processes [26,[29][30][31][32].…”

Roughening the substrate surface is essential for thermal sprayed coatings. In this regard, sandblasting has established itself as an easy to use surface conditioning procedure. The quality of the obtained roughness depends on the conditions of the sandblasting material, adjusted parameters, and the kind of the process execution (manual or mechanical). These preconditions limit the reproducibility of the roughness obtained. Sandblasting causes residual compressive stress and may also lead to the inclusion of sand particles and notches in the roughened surface, which affects the interfacial properties of the coating, as well as the flexural strength of the coated parts. The hardness of the roughened surface plays, thereby, an important role. However, in order to reliably avoid these effects, microfinishing can be used as an alternative to generate a homogenous roughened substrate surface, control the induced residual stresses, and increase the reproducibility. In addition, the roughened surface pattern can be produced during the chip forming process of the to-be-coated parts. The utilization of the appropriate combination of machining processes and parameters should lead to the required surface pattern and thus to an enhanced coating adhesion and flexural strength of the coated part. The induced residual stresses and the quality of the obtained surface roughness have a significant influence on the coating adhesion and the lifespan of the coated parts. This paper aims to analyze, as a first step, the effect of the turning and microfinishing on the surface conditioning of the bearing steel 100Cr6 (AISI 52100). The investigation concludes by comparing the microfinished with the sandblasted surfaces with regard to the interface to and the adhesion of the WC–Co high velocity oxygen fuel (HVOF) sprayed coatings on them. Surface conditioning plays a decisive role by the induced residual stresses and the elimination of adhesion defects.
