Analysis of plated layer’s effects on the structure resistance to corrosion

This paper presents the laboratory testing of protective effects that the plated layer had on the structure resistance to corrosion by using the weighing method, i.e. the method of mass loss. The described procedure refers to preparation of samples, their exposure to aggressive atmosphere of the salt chamber and analysis of obtained results. According to the properties of the base material and its reduced stability in the experimental conditions, it is confirmed that the use of plated layer was required to improve the structure resistance to corrosion and to protect the base material

The influence of mixing water and abrasives on the quality of machined surface

This paper shows the impact of mixing water and abrasives in water jet cutting process on the quality of the machined surface. The tests were done with polymer material SIPAS, where the influence of cutting parameters was researched (cutting pressure, cutting feed and abrasive mass flow). The surface roughness was measured on several zones, regarding the depth of materials, because the roughness is increased with the material thickness

Application of water jetfor cutting polymer materials

Due to the nature of polymeric materials, during thermal cutting processes it leads to their melting, and therefore appear errors in the final product. This paper presents a “cold” process of cutting polyamide 6 ie. SIPAS 60, where there are given the characteristics of materials and guidelines for satisfactory quality of process. The authors made the cut experiment 32 were they changed the cutting parameters (cutting pressure, cutting feed and abrasive mass flow); the surface roughness was measured by the depth of material, because the roughness changes with the thickness of the material to be cut
