Integrated Quality Ensuring Technique of Plasma Wear Resistant Coatings

Abstract

We propose the technique of guaranteed quality wear resistant plasma coatings of high-chromium powder material. The appropriate system of engineering models had to be designed in order to obtain the summarized results, as well as to manage the parameters of quality indicators at all stages of the technological processing procedure. Thus, surface roughness was accepted as a criterion in the model development at the stage of preliminary mechanical processing before spraying coatings. The model of plasma coating process proper takes into account the influence of spraying on the main quality indicators, such as adhesive strength, porosity, and the level of residual stresses. The engineering model of finish abrasive grinding is based on ensuring the desired value of the surface roughness parameter provided the geometric and dimensional accuracy of details was achieved.

Assessment of the environmental situation on the territory of CJSC KTK-R and in the area of its direct influence

“…Of all the substances entering the biosphere, heavy metals should be considered the most dangerous pollutants. They are not decomposed in the environment, but gradually accumulate in the soil, plants, animals and eventually enter the human body through the trophic chain, causing severe poisoning and disease [12][13][14][15].…”

Assessment of the impact of poultry farms on some environmental components by the example of CJSC Novorossiysk poultry farm

“…Hygienic assessment of the impact of odour emissions on public health, as well as the control of these emissions, due to the ever-expanding production of poultry farms and the problems of their waste disposal, are becoming increasingly important and require further study [11][12][13][14].…”

Scientific basis for assessing reliability of water reservoir

“…The lead channel is covered with reeds. Suffocation processes occurred on the slopes due to leaching of the filtration stream [9][10][11][12].…”
