Description
The article shows the possible ways to control the quality of plasma coatings, such as modulation of the electrical parameters of indirect and remote arc plas-ma torch, vibration, thermal and electro-coating pro-cess, etc. Theoretically based on mathematical model-ing and experimental results of the effect of modula-tion of electrical parameters of the plasma deposition and hardening coatings on their quality are listed. We also developed new high-saving technologies and equipment for applying and hardening coatings on in-ner and outer compact surface on flat, cylindrical and shaped the surface of parts of friction pairs

ENERGY-LOADING OF DISKS IN FRICTION PAIRS OF “DISC-PAD” OF BRAKING DEVICES IN VEHICLES (part two)
DescriptionIn the materials of the article we mention the regularities of changes in the volume and surface solid temperature gradients and self-ventilated brake discs and illustrate their impact on the main operating parameters of the friction pairs of disk-to-pad brakes of the A 172 bus; the relationship between thermo-physical parameters of polished and matte surfaces with areas of brake discs of various types. The influence of the type of tests on the pairs of loaded with energy friction disk and pad brakes of the vehicle. We have set the intensity of heat exchange processes from the surfaces of the brake discs of various types. It is shown that this leads to increased surface temperature gradient. The volume and the surface temperature gradients of the brake discs were determined with the involvement of the hypothesis of summation of temperatures on the surface when you post the generated electric currents. It was found that in the surface layer of the working surface of a solid brake disc at its pulse heating under the influence of the temperature of the flash nucleate cracks due to the thermal fatigue of the material of the disk. The features of the design of the brake discs were considered as well. On the basis of the calculation and the experimental data we have shown a correlation between the emissivity of brushed and polished surfaces and their areas in the disk-to-pad brakes when using solid and self-ventilated discs

Description
The article considers discrete automatic machines with memory, designed for searching the values of parameters of the system optimizing a merit figure of the system, described by some criterion function. The problem of multiple parameter optimization is shown as a problem of discrete optimization by means of representation of values of parameters of the optimized system in the form of a set of discrete values with a specified step of digitization
