… influence of the coating thickness, deposited by arc-PVD- technology, on the wear resistance of coated cemented carbide inserts in three different turning operations. An additional effort has also been made to develop a new test method for evaluating flank wear resistance. Three …
… been noted that the life span of the tool is shortened as a result of abrasive wear that occurs during the attachment process of the ignition coil. An investigation of the possibility of manufacturing the mounting tool with a 3D-printer is undertaken in cooperation with ÅF, a …
… suitable for decorative coatings since ceramic coatings are often hard and wear resistant, and since modulations in oxygen content or incorporation of small ions could give bright colours. The aim of this report was to investigate the relationship between process parameters and …
… cylinder liner and rank these combinations of materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C. The experimental tests were performed with a so-called pin-plate, where used oil with addition of an …

… At the same time the maneuver torque should be retained or better and the wear should not be worse. The project begins with a theoretic investigation of valve forces, maneuver torque and seat design. A manufacturing drawing was made in Pro ENGINEER and handed over to SOMAS AB …
… The parameters of the textile material would meet was to hold high friction, wear resistance, adhesive while being environmentally friendly. Background material was presented and a set of requirements and concepts that were evaluated. The concept that received the highest rating …
… the coatings can be used as a protective layer that will reduce or prevent wear on selected parts of the naval powertrains. As a basis for the essay, nanotechnology is described, as well as different reasons that wear occurs and application techniques for coatings The conclusion …

A preliminary study
… have been studied as well such as hardness, friction coefficient, fatigue- and wear resistance. The cost of some of the different surface finishing techniques has been studied as well, because in order to be interesting their price must match what improvements the technique …
… bench that can run around the clock in order to be able to test things like wear and service intervals and other things that require that the test interval is long. In this report, I have deepened me in how to measure the torque on a rotating shaft. This specialization has led …
