Abstract: One of the most frequently performed orthopaedic procedures in Poland and in the world is hip arthroplasty. Correct placement of the implant in the bone tissue and initially positive postoperative results do not determine the durability and effectiveness of the above method of treatment. [..] Read more

Abstract: The article presents the results of tests of the coating material intended for the elements of boilers in the power industry (water walls, steam superheaters). The coatings were applied by thermal spraying, which is one of the basic technologies in surface engineering. [..] Read more

Abstract: Galvanizing still plays an important role in surface treatments. The thickness and quality of the zinc layer is the basic monitored property of materials treated in this way. [..] Read more

Abstract: The aim of this work is to determine the possibility of using a digital microscope as a non-contact measurement for the surface quality of cores, and thus to predict the surface quality of pre-casted holes and cavities in manufactured castings. In this study, the test cores were manufactured on a laboratory shooting device with a variable shooting pressure in the range from 0 bar up to 10 bar. [..] Read more

Abstract: This paper deals with the structural and composition differences of two types of fluoride conversion coatings on two types of bulk magnesium materials. The bulk magnesium materials used were powder metallurgy cold compacted magnesium and sintered magnesium materials. [..] Read more

Abstract: This paper aims to characterize Zn-Mg-Al based coating by profile analysis and determine its thickness as a basic property of the coatings. The most frequently used method for its determination is optical microscopy, but it is time-consuming and destructive. [..] Read more

Abstract: Anti-corrosion protective polymer thin films are used to prevent metal contacting with an aggressive environment. It is known that the density of the polymer film coating can be controlled at the stage of formation its. [..] Read more

Abstract: In recent years, there has been an increased interest in technologies for the production of titanium ceramic materials with properties, the level of which in terms of price-quality ratio exceeds the level of similar materials based on other metals. The strength of the bond with the metal in modern titanium ceramic products corresponds to the level of cermet systems based on noble metals or alloys without them. [..] Read more

Abstract: The HVOF (high-velocity oxygen fuel) technology is one of the most used processes for carbide-based coatings application. These coatings are suitable, for example, to replace hard chromium plating. [..] Read more

Abstract: High velocity oxy-fuel spraying (HVOF) being one of thermal spraying techniques, is deployed in many commercial applications mostly for very hard wear and/or corrosion resistant coatings. Supersonic speed of the spraying jet combined with temperatures around 5500 K is utilized to spray most metals, metallic alloys, cermets and superalloys [1-3]. [..] Read more

Abstract: Thermofriction hardening of steels is a modern technology for extended use in the production of various parts, the surfaces of which require increased wear resistance. The presented research continues the work of the authors on the study of the transformation and properties of metal structures that have received frictional processing; identification of physical mechanisms of steel hardening and the formation of ideas about residual manifestations and support of the strength heredity of intense frictional contact in the subsequent life cycle of the part at the final operations of its shaping and operation under conditions of thermophysical loading similar to tempering.

Abstract: The trend to use modern materials and technologies in the development and construction of rail vehicles leads to testing new suitable alternatives for surface treatment of strain parts. Within the research project, suitable thermally sprayed coatings as alternatives for former surface treatment of selected components of rail vehicles are tested. [..] Read more

Abstract: Laser treatment of metallic layers can significantly change the morphology of the surface. Due to the action of the laser beam, the surface roughness considerably increases. [..] Read more

Abstract: Assessment of the surface of the car’s element is an attempt to applythe image processing and machine learning methods for analysis of surface layer quality. In presented experiment set of the images with damaged surface layer of vehicles were used to design and train CNN for detection of scratches. [..] Read more

Abstract: Wire electrical discharge machining (WEDM) is non conventional technology in which the electrical discharges occurring between the wire electrode and workpiece allow to machine difficult to cut material. The shape accuracy of cut high parts is one of the major limitations of WEDM. [..] Read more

Abstract: A characteristic feature of the beam technologies is that the treatment of materials occurs as a result of the impact of the concentrated energy flux. By controlling the energy flux, the selected areas of the surface can undergo the treatment process. [..] Read more

Abstract: Magnesium and its alloys is a class of materials, which is still one of the most prospective hydrogen storage (HS) compositions. This is due before all to their high hydrogen sorption capacity and low cost. [..] Read more

Abstract: The jarosite sample was subjected to characterization by dichromatometry, gravimetric analysis, XRD, AAS, ICP, SEM and EDS. The particles of this compound are spherical and made up of rhombohedral microcrystals. [..] Read more

Abstract: The growth of industrial production dictates the need to search for new technologies for environmental protection. Complex titanium-containing reagents have proven themselves well in wastewater treatment processes of various origins, however, the processes of obtaining such reagents for the needs of water purification are practically not described in the literature.
