Purpose: Cryogenic engineering is gaining more and more interest in various industry sectors, which leads to an intensive search for effective solutions. The article presents the findings of mechanical testing conducted on glass-epoxy laminates at room temperature and after long- term contact with liquid nitrogen. Design/methodology/approach: To compare the impact properties and flexural strength,...
Purpose: The aim of the work was roughness investigation of the surface of developed oesophageal prosthesis before and after texturing, to estimate its influence on future application of prosthesis. Design/methodology/approach: Linear, mechanical contact-measurement method and, for verification, optical profile measurement in confocal microscope were used in the work. Findings: The roughness investigation...
Purpose: of this paper is description of stresses in brazing joints of different physical and mechanical properties and evaluation of microstructure and mechanical properties of large dimensional vacuum brazed joints of WC–Co (ISO K05), Fe-TiC sinter plates (Ferro–Titanit Nicro 128) and precipitation hardened stainless steel of 14-5 PH (X5CrNiMoCuNb14-5) using copper as the brazing filler metal. Design/methodology/approach:...
Purpose: The aim of this work is to study of constructional model of internal prosthesis of oesophagus with determined functional features; the prosthesis will replace the upper part of the digestive system – the oesophagus. Design/methodology/approach: Constructional model of internal prosthesis of oesophagus was worked out in the basis of physiological build of oesophagus considering surgical techniques...
