Abstract:
This research paper deals with an effect of injection mold core/cavity surface and their additional treatment on selected optical properties and surface quality of these tool parts. Used mold cavities were made from tool steels 1.2343 (chromium-molybdenum-vanadium-silicon steel with good hardenability) and 1.2083 (martensitic steel with high chromium content), their surface was polished to the roughness of Ra = 0.08 microns (manufacturer guaranteed mirror finish).

Abstract:
The purpose of the study is to identify possible changes in different elementary powders (Al, Ti, Co, Cr, Ni, Fe) after being compacted by cold spray kinetic deposition. A deep analysis on the microstructure of the materials prior and after the deposition was performed through Scanning Electron Microscopy, Energy-Dispersive X-Ray Spectroscopy, Electron Channeling Contrast, X-ray Diffraction, Differential Scanning Calorimetry and microhardness tests.The results indicate that there are noticeable alterations in the microstructure of the materials due to plastic deformation processes which occur during the cold spray deposition, within the material presented up to 58% increase in hardness.

Abstract:
The service life of components used in the construction, mining or agricultural industry depends on several factors. Primarily lifespan is influenced by the type of wear to which the parts would be subjected (for example abrasion) and environment in which components perform their function. [..]

Abstract:
Composite (Ni) + Ni3Si coatings on C45 steel-substrate could be easily developed via three-step technology: electrodeposition of nickel interlayer, sediment co-deposition of Ni+Si and subsequent vacuum annealing at 980 C for 5 h. The results of hardness measurements showed that as-plated Ni+Si coating was 1.7 times harder than the electrodeposited Ni coating, but the hardest was (Ni) + Ni3Si coating (820 HV) due to the presence of the super hard Ni3Si phase.

Abstract:
Titanium dioxide (TiO2) is one of the most useful materials in various applications related to catalysis, electronics, photonics, sensing, and medicine. TiO2 is characterized by high chemical stability, outstanding optical and electrical properties, a non-toxic nature, and ease of mass production, and this is what causes it to be successfully used as a photocatalyst in many fields such as anti-bacterial applications, water purification, the decomposition of various organic pollutants, and solar cell applications TiO2 thin films can be prepared by a variety of methods, such as the sol–gel method, pulsed laser deposition, chemical vapour deposition, spray pyrolysis, and sputtering techniques.

Abstract:
An original method was recently developed for an assessment of residual stresses in case-hardened steels based on S-N curves of hardened and virgin samples along with the measurement of location of fish-eye crack centres. This method is applicable only when the surface of virgin specimens is sufficiently smooth to avoid the initiation of fatigue cracks from large surface defects. [..]

Abstract:
The work presents the effects of the change of the laser cladding parameters on microstructure, chemical composition and mechanical properties of Inconel 686 overlays (coatings). To obtain the best quality of these coatings the various parameters of laser cladding such as the power density of the laser beam, the laser beam velocity and overlapping ratio of the weld tracks were applied.

Abstract:
Cold Gas Dynamic Spraying (CGDS) method was used in order to obtain very dense and good adhesive CoNiCrAlY-coatings deposited onto nickel-based alloy and subsequently remelted by electron beam (EB) up to depth of about 90 µm. The CGDS process- a relatively new coating technology is based on the high velocity impingement of small solid particles on the substrate. [..]
