“…The topography of the surface with different surface qualities can be easily expressed using surface profile parameter Ra [20][21][22][23]. The values of surface roughness, Ra, were 1.16 × 10 −6 m for TiCN coated samples and 1.32 × 10 −6 m for as-sintered samples.…”

The present paper deals with the sliding wear behaviour of prealloyed chromium sintered steel (Fe-1.5Cr-0.2Mo) with graphite powder added in the amount of 0.7%. The wear characteristics, such as profilograms, wear tracks morphology and wear curves of the as sintered specimens and TiCN coating were investigated through pin-on-disk tests. The specimens were sintered in pusher furnace at the temperature of 1453 K for 2400 s in a nitrogen-hydrogem atmosphere. Dominant bainitic microstructures with evident features of plastic deformation at the worn surface were detected. The coating of the investigated prealloyed steels increases the wear resistance in comparison with the as-sintered state according to the wear curves. Microstructural and EDX analyses confirmed that delamination and oxidation wear are the main wear mechanism in wear tests.

“…To achieve the economically effective process with the least energy losses, it is necessary to determine correctly the technological parameters of the process. As optimization technologies for various kinds of materials are given by relation criteria, the cutting speed, focusing tube diameter, abrasive mass flow rate and optimized pump pressure were selected [9,10]. The technology factor for the selection of (17):…”

The submitted paper aims to clarify the abrasive waterjet technology, particularly from the point of view of produced surface topography. It provides a new insight into the deformation process caused by the effect of abrasive waterjet and into the possibilities of using the surface topography for solving the issues of optimization of the process. The subject of study is a system of cutting tool, material and final surface topography and optimization of their parameters. The cutting or disintegrating tool of abrasive waterjet technology is flexible. The trajectory of its cut traces is strictly determined here by disintegration resistance at critical moments of tool-material interaction. The physico-mechanical character of the interaction within the cut will manifest itself in the final surface condition. This process can be re-analysed by measuring the selected elements of topography and roughness on the final surface, namely depending on the depth of the cut, technological parameters of the tool and mechanical parameters of the material. The mentioned principle is the basis of the presented solution. It lies in the analytical processing and description of correlation interrelations between set technological and measured topographical quantities in relation to the depth of cut and the type of material.

“…The conclusions mention that further research is needed to generalize the model achieved. The topology of the cut zones was investigated in research [17] and [18], for AWJM of stainless steel parts. New methods for estimating the surface quality were proposed based on experimental analysis of the surface profile.…”

This paper presents an experimental investigation on the abrasive waterjet machining (AWJM) of Hardox steels. A full factorial plan was designed and carried out to determine how the traverse speed, the material thickness, and the material type influence the surface roughness. Two materials were machined during the experiments: Hardox 450 and Hardox 500. The experimental data were analysed using statistical methods, and a mathematical model was obtained. Additional experiments were made to validate the model. The results proved that the analysis is accurate and the mathematical model will be a useful tool in industrial environments for process planning when abrasive waterjet machining is used for the considered material.
