Purpose: The aim of the paper was investigation of the effect of Cu addition on GFA (Glass Forming Ability), structure, magnetic and mechanical properties of amorphous Fe-Co-B-Si-Nb alloy. Design/methodology/approach: The following experimental techniques were used: differential thermal analysis (DTA), transmission electron microscopy (TEM) and X-ray diffraction (XRD) method, measurements of magnetic...
Purpose: The purpose of this paper was to analyse the surface morphology and optical properties of polyoxadiazoles thin films. Design/methodology/approach: A few different conducting polymers were dissolved in N-methyl-2-pyrrolid(in)one. Then the solutions were deposited on a glass substrate by spin coating method with a different spin rate. Changes in surface topography and optical properties were...
Purpose: The paper presents the comparison of the abrasion wear resistance of the laser alloyed hot work tool steels X40CrMoV5-1 and 32CrMoV12-28. Design/methodology/approach: The tribological wear relationships using pin-on-disc test were specified for surface layers subject to laser treatment, determining the friction coefficient, and mass loss of the investigated surfaces. Findings: The performed...
Purpose: The aim of the paper is to investigate the influence of the heat treatment on the structure, mechanical properties and corrosion resistance of the steel X10CrNi18-8. Design/methodology/approach: The investigated steel was solution heat treated at temperature 1050°C with water cooling and it was analysed the susceptibility to intergranular corrosion at temperature 700°C. Structures were investigated...
Purpose: The study contains the analysis of TiO2 and SiO2 surface modification impact on physical and chemical characteristics of Ti-6Al-7Nb alloy samples in the solution simulating cardiovascular system. Design/methodology/approach: Sol-gel coatings were selected on the ground of data taken from literature. The base of stock solution consisted of silicon dioxide precursor SiO2 (TEOS) and titanium...
