Abstract Laser ablation of galvanized steel at a wavelength 343, 515 and 1030 nm was compared for single as well multiple picosecond laser pulses. The characteristics ablated craters, such rate, crater shape chemical composition, in relation to the processing parameters were studied. Surface morphology craters characterized with help confocal scanning microscopy electron microscopy. Chemical co...

In this paper, unique tests into the production of galvanised steel wires in industrial conditions were presented. It was demonstrated that three phenomena occur during wire-drawing process at high speeds: namely, zinc sticking to surface drawing drums, coating grinding caused by a larger friction area between tool and material, combined with detachment calibrating part die until wire breaks is...

In order to form model aluminide coatings for studying critical issues related to their high temperature oxidation and corrosion performance, a laboratory chemical vapor deposition (CVD) procedure is being used to more rigorously control the coating process in terms of composition, purity and microstructure. One ferritic (Fe-9Cr1Mo) and one austenitic alloy (304L) were selected as substrate mat...
