Abstract:

The flame used in combustion flame spraying is typical of a high-temperature free jet. The flow fields of free jets are multi-phase flows that couple the mass and heat transfer. The analytical and numerical solutions to turbulent flows are engineering approximations. This work uses Prandtle’s mixing-length theory to describe the flame spreading of free combustion spray jet and uses nozzle spray model to describe the distribution of the powder particles sprayed from powder nozzle to the substrate surface. The nozzle geometry and the parameters determine the distribution of the powder particles.

Abstract:

The process of gas-thermal spraying of coatings made of wire materials has been studied by determining rational regimes to increase the wear resistance of surfaces of vehicle parts. It is determined that the main factors influencing the wear resistance of steel gas-thermal coatings are the cooling rate of steel and the concentration of alloying elements. It is shown that in order to obtain wear-resistant sprayed coatings from alloyed structural steels it is necessary to achieve certain conditions of coating formation, namely: heating and spraying temperature of wire, cooling rate of molten par

The article studies deformation behavior in friction-cyclic loading of composite surface layers, that were made of materials with shape memory effect (SME). We have demonstrated that a multi-layer composite surface layer (Ni - TiNiHf - TiNi), which was formed by the high-speed flame spraying of mechanically activated powders with subsequent thermomechanical processing, enhances the wear resistance and fatigue strength of products. This is due to the special properties of materials with shape memory.

Abstract:

Abstract Heat transfer studies have been conducted for cooling systems with coatings made of natural materials, depending on the parameters of the detonation flame of a thermal tool and the thermophysical properties of natural materials. Cooling systems with porous coatings of mineral media powders (quartzites, granites, teschenites, tuffs, marbles) had been developed, which were applied on a metal surface at temperatures up to (2500 ÷ 3500) °C and flow rates up to 2500 m/s by hot flames emanating from combustion chambers and nozzles. The holography and high-speed filming method has been used

Abstract:

Cladding-based repair has been found to be superior than welding or flame spraying repair approaches in terms of extending die life. In this work, two different alloy powders, that is, CrNiW and CrNiFeAlZr were coated on H13 steel using laser cladding. The laser power, powder feed rate and scanning speed were varied and the clad dimensions, aspect ratio and dilution percentage were measured. The microhardness found in the CrNiW clad is 834 ± 20 HV0.5, which is higher than that of the CrNiFeAlZr clad (780 ± 20 HV0.5) as well as the substrate clad (548 ± 20 HV0.5). CrNiW clad has a higher microh
