“…The layer is applied by screen printing and cured at high temperature. The commonly used coating called Grafal 255, which contains about 35% of graphite additive and no additives acting as friction modifiers, can serve as an example [38]. New types of coatings contain molybdenum disulphide (EvoGlide type) and other friction-modifying chemical compounds [38].…”

“…Research results presented in the thesis by Kotnarowski [39] confirm the possibility of getting very favourable effects also by using molybdenum disulphide. The influence of the type of layer covering the load-bearing surface of the piston on the wear of mating surfaces and friction losses has been the subject of intensive research [38,40,41]. Research results obtained in these studies unequivocally confirm the positive role of standard coatings in reducing the possibility of piston seizure in the cylinder and reducing the wear of the cylinder surface under normal engine operating conditions.…”

This work presents the factors determining cast iron, and particularly austenitic high-alloy cast iron as a construction material, which is ranked among the leading casting alloys of iron with carbon, mainly due to its very good service properties, which makes it dedicated as a material for automotive castings, pipe and fitting castings and components resistant to elevated temperatures, corrosion and abrasive wear. Construction materials currently used in industry have increasingly better properties and their potential is depleting quickly. This forces the manufacturers to adjust the requirements and production capabilities of cast iron using the most modern technologies that give the expected beneficial economic and operating effects. The paper quotes the results of research in the field of the offered technologies that give special surface features to machine parts made of cast iron by modernising the parameters of the technological process of obtaining high-alloy austenitic cast iron, i.e., by applying coatings, as well as by appropriate surface treatment, the aim of which is and reinforce the material surface with those properties which are important in a given application.
