BIULETYN INSTYTUTU SPAWALNICTWA No. 3/2019 21 Tomasz Poloczek, Artur Czupryński The Analysis of the Abrasive and Erosive Wear Resistance of Abrasion-Resistant Sheets Abstract: Te article presents results of tests concerning the assessment of the abrasive and erosive wear of abrasion-resistant plates fabricated by Polish and overseas manufacturers. Materials used in the tests, i.e. the Castolin CDP® 1001, CDP® 4666 and CeraMetal® HCCr plates were made using the automated arc welding technology. Reference materials used in the tests were both Polish and overseas abrasion-resistant plates. Te analysis of the results of hardness tests performed in accordance with PN-EN ISO 6508-1:2016 as well as of the results of abrasive and erosive wear tests performed in accordance with ASTM G65-00 and ASTM G76-04 enabled the indication of materials characterised by the most fa- vourable functional properties enabling operation under conditions of intense metal-mineral abrasive wear.

Te market ofers a wide range of materi- als resistant to various types of wear including erosion, abrasion or corrosion, ofen interrelat- ed under certain environmental and load-re- lated conditions, to which a given element is exposed. Te selection of an appropriate mate- rial satisfying assumed functional requirements entails thorough analysis aimed to protect a giv- en structure against wear in its work environ- ment. Materials characterised by appropriate abrasive wear resistance and other function- al properties are obtained in a complicated technological process. Te primary application areas of abrasion-resistant sheets include the extractive and power engineering industries as well as the production of cement, where such sheets are used to make chutes, concrete mix- ers or various rotors. Related tests concerning the wear of machinery elements revealed that abrasive wear constitutes approximately 50% of defects. As can be seen, the reduction of abra- sive wear through an increase in hardness and strength/resistance leads to signifcant materi- al and, consequently, fnancial savings. Materials presently applied in environments characterised by high abrasive and erosive wear include abrasion-resistant steels Hardox®, mgr inż. Tomasz Poloczek (MSc Eng.); dr inż.
