To obtain tribologically useful surface layers (SL) electrochemical treatment called anodic hard coating (AHC) is applied. The formation of the hard oxide layers on aluminium alloys increases the range of its application in different fields of industry. The possibilities of dripping some lubricating agent during preparation of the coating makes it possible to apply AHC to sliding couplings which do...
The article presents the use of a new SCGC method and the JKC computer programme to estimate measured surface stereometry of machine parts, mainly for industry quality. On the basis of burnishing surfaces the qualities of the new method are presented, namely: visualisation which enables one to imagine the measured roughness area, location of the most important evaluation parameters (distribution of...
The paper presents the results of investigations on the effects of various cooling methods on smoothness and stresses in a surface layer of the work material in the process of surface grinding. Three methods of wheel cooling have been investigated: conventional cooling with fluid flux, a new method - the fluid is supply through radial nozzles made in the course of high-pressure moulding the grinding...
Titanium alloys are characterised by a poor wear resistance when interacting with other construction materials, and by a great tendency to become scuffed. Laser alloyed surface layers, due to forming hard ceramic particles spaced in ductile matrix, have a lower wear intensity as compared to conventional alloys and enables application of titanium alloys as a part of tribological couple. The aim of...
Electrodischarge machining (EDM) is widely used in industry. This manufacturing method enables high accuracy and low roughness of machine parts and allows for manufacturing elements of highly sophisticated shape and made of ultra-hard materials. It is also limited in use because of unfavorable properties of surface layer after the EDM. The results of geometric surface structure, metallographic structure,...
The study presents investigation results of technological quality of teeth of a cylindrical gears made of 18CrMo4 steel, carburized, quenched and tempered, and grinded with use of profile dividing method on grinding machine of Höfler Rapid 900 type. It have been included investigation results of geometrical accuracy and selected properties of surface layer of the teeth after hobbing operation, thermal-chemical...
