Abstract
U radu je opisan PACVD postupak prevlačenja i mogućnost povećanja otpornosti na abrazijsko trošenje visokolegiranih alatnih čelika za hladni rad. Korištena je TiCN prevlaka koja se nanosila na osnovni materijal izrađen od čelika Böhler K110 (EN X155CrVMo12-1), odnosno Böhler K390PM dobiven metalurgijom praha. Opisan je postupak ispitivanja otpornosti na abrazijsko trošenje metodom “suhi pijesak/gumeni kotač“ kako bi se utvrdio utjecaj osnovnog materijala, pripreme površine i debljine prevlake na otpornost abrazijskom trošenju. Uz ispitivanja otpornosti na abrazijsko trošenje, ispitavala se i hrapavost površine uzoraka pertometrom, debljina nanesenih prevlaka kalotestom te adhezivnost prevlake na tvrdomjeru Rockwell C. Tragovi trošenja na ispitnim uzorcima su analizirani na stereomikroskopu dok je njihova mikrostruktura analizirana na svjetlosnom mikroskopu. Ispitivanja su pokazala dobru adhezivnost TiCN prevlake na oba osnovna materijala, kao i najveći utjecaj vrste osnovnog materijala i debljine prevlake na otpornost abrazijskom trošenju.
Abstract (english)
In this work PACVD (Plasma-Assisted Chemical Vapour Deposition) procedure is described, as well as the possibilities of improving resistance to abrasive wear of high-alloyed cold work steels. Böhler K110 (EN X155CrVMo12-1) and Böhler K390MC steels are applied as the base for TiCN coating. The procedure of examining abrasive wear resistance via “dry sand-rubber wheel“ method is described. The purpose of examining abrasive wear resistance is to determine connection between base material, surface preparation, coating thickness and abrasive wear resistance of high-alloyed cold work steels. Along with method “dry sand-rubber wheel“, surface rougness via perthometer, coating thickness via Calotest and coating adhesion via Rockwell C hardness tester are also examined. The surfaces of worn samples are analyzed using a stereo microscope while their microstructure is analyzed using an optical microscope. Tests showed good adhesion of TiCN coating on both base materials. Type of material applied as base for TiCN coating and coating thickness showed as most important contributors to the abrasive wear resistance.
