This paper presents the results of testing mechanical and structural characteristics of plasma spray coating Al2O328wt.%MgO. Metal oxide MgO in a complex oxide Al2O328wt.%MgO modifies the properties of Al2O3 ceramics by forming spinel MgAl2O4 with excellent biomedical characteristics. The coating layers were deposited by atmospheric plasma spraying process (APS) on steel substrates of stainless steel X15Cr13 (EN 1.4024). The aim of this study was to examine the effect of the strength of the plasma current (700A, 800A and 900A) on the mechanical properties of the Al2O3MgO coating, pore content and microstructure of the layers. Testing microhardness of the layers using the HV0.3 method, the bond strength using the tensile method and microstructure using optical microscopy (OM) and scanning electron microscopy (SEM) have confirmed that, by controlling the plasma current, layers of the coating system Al2O328wt.%MgO can be deposited with good mechanical and microstructural characteristics s...uitable for use in manufacture of implants.
U ovom radu su prikazani rezultati ispitivanja mehaničkih i strukturnih karakteristika plazma sprej prevlake Al2O328tež.%MgO. Metalni oksid MgO u kompleksnom oksidu Al2O328tež.%MgO modifikuje osobine Al2O3 keramike formiranjem spinela MgAl2O4 odličnih biomedicinskih karakteristika. Slojevi prevlake su deponovani atmosferski plazma sprej procesom (APS) na čeličnim podlogama od nerđajućeg čelika X15Cr13 (EN 1.4024). Cilj ovog rada je bio da se ispita efekat jačine plazma struje (700A, 800A i 900A) na mehaničke osobine prevlake Al2O3MgO, sadržaj pora i mikrostrukturu slojeva. Ispitivanja mikrotvrdoće slojeva metodama HV0.3, čvrstoće spoja zatezanjem i mikrostrukture optičkom mikroskopijom (OM) i skening elektronskom mikroskopijom (SEM) su potvrdila da se sa kontrolom plazma struje mogu deponovati slojevi sistema prevlake Al2O328tež.%MgO dobrih mehaničkih i mikrostrukturih karakteristika pogodnih za primenu u eksploataciji za proizvodnju implanata.
