Abstract

Research were focused to different zinc coatings quality put on iron alloys (cast iron, steel). In the paper the galvanic, hot-dip and lamellar zinc coatings were compared. The complex investigation method consisted in proper coating preparation (in industrial conditions) on specially prepared samples and evaluation of surface state/topography that has essential influence on other coatings specific properties, like corrosion resistance, wear resistance, resistance to mechanical damage, etc. Additionally also mechanical, tribological and anticorrosion properties were determined (in other paper). For surface/topography state evaluation three different methods were used: contact profile recording instrument Perthometer Concept (MAHR) with 3D software, PhaseView optical assembly for 3D surface scanning and MarSurf WS 1 – the high-precision, non-contact measurement of surface texture using the principle of white-light interferometry. During tests the basic parameters describing roughness and waviness together with isometric surface image were determined. Advantages and disadvantages of each method were compared. It was stated that although the most precise results are achieved by contact profilometer application also using the ZeeScan system enable the reliable surface evaluation but in much shorter time.
