“…This is also confirmed by EDS microanalysis results (Table 3) Hardfacing made with string beads (Fig.1-2) had numerous chromium carbide type precipitates of (Fe,Cr)7C3 that is characteristic for the materials deposited on the structure of chromium cast irons [19][20][21]. Precipitations of the carbide had varied shape and placement of the cross-section of the deposit.…”

The paper presents the capabilities of welding techniques to creating properties of wear resistant high chromium cast iron alloy. The use of the right kind of welding sequence allows you to change the structure and properties of the obtained welds. Tests were conducted for one type of additive material in the form of self shielded core wire. In order to determine the effect of the type of welding sequence on the properties of welds performed welding using string bead and weave bead. The resulting weld was tested on hardness and research structure in an optical microscope. In the following studies have been made erosive tests wear of made hardfacing. String beads gave structure rich in carbides and harder about 270 HV of the weld with weave bead. Also, wear resistance was nearly twice as better for welds made with string beads. In the experiment a decisive role in the resistance to wear plays a high hardness of the deposit and the presence of carbides in its structure. Changes in the basic parameters of the deposition process allows for the formation of structure and properties of hardfacing welds in a wide range.

“…Sometimes, the material surface is also tested to ensure the accuracy of results, as knowing the nature of variation makes it easier to identify the type of wear and tear. Microscopic and spectroscopic examinations are conducted to evaluate microstructures and phase transitions [12][13][14][15].…”

Analysis and Comparative Assessment of Basic Tribological Properties of Selected Polymer Composites

Phenomena occurring in the contact area between two mating bodies are characterised by high complexity and variability. Comparisons are usually made between parameters such as the coefficient of friction, friction force, wear and temperature in relation to time and friction path. Their correct measurement enables the proper evaluation of tribological properties of materials used in the friction pair. This paper concerns the measurements of basic tribological parameters in the friction of selected polymer composites. Knowing the tribological properties of these composite materials, it will be possible to create proper operating conditions for kinematic friction pairs. This study investigated the coefficients of friction, friction force and temperatures of six polymer composites: cast polyamide PA6 G with oil, PA6 G with MoS2, polyoxymethylene POM with aluminium, polyethylene terephthalate PET with polytetrafluoroethylene PTFE, PTFE with bronze, and PTFE with graphite. The friction surface was also examined using an optical system and computer software for 3D measurements. As a result, PA6-G with oil was found to be the best choice as a composite material for thin sliding coatings.

“…The most widely used materials are based on Fe, Ti, Co, Ni that are alloyed with different chemical elements such as Cr, B, Ti, Si, Mo, Mn, W, V, Nb. They lead to changes in mechanical, tribological and corrosive properties [21][22][23]. Due to economic reasons, it is recommended to use Fe-based welding consumables.…”

This paper investigates properties of single-and double-layer pad coatings deposited on cultivator points. The coatings were deposited by manual metal arc welding (MMA) with ESAB OK. 84.58 coated electrodes using an inverter welder, DEDRA DESi201. Tribological properties were determined with a THT 1000 tribometer. A ballon-disc friction pair was used. Experiments were performed in room temperature, with the sliding speed set equal to 0.3 m/s and two loads: 5 and 20 N. In addition, hardness was measured on the surface and in the cross section of samples by a Rockwell hardness test method (scale C). Surface roughness was measured before and after friction, and post-friction surface topography was examined under microscope. Impact strength tests of the coatings with single-and double layers of pads were performed. The tools and IT algorithms were used to collect and process the results of experimental research.
