The two-dimensional problem on the collision of a potential ideal-liquid jet, outflowing from a reservoir through a nozzle, with an infinite plane obstacle was considered for the case where the distance between the nozzle exit section and the obstacl

The effect of preliminary treatment of a steel substrate on the dynamic properties of cathode jets during electrospark deposition is studied. The energy of cathode jets is determined indirectly using the strain hardening of the electrode surface laye

The relationship between deposition temperature, coating inhomogeneity, and temperature of cathode spots is studied. It is shown that the spark deposition of coatings proceeds in the area of cathode spots; therefore, the substrate temperature has an

A jet model based on approximations of velocities, satisfying the continuity equation, and on the integral momentum equation is presented. The solution for the jet dynamics turned out to be nonmonotonic: as an obstacle recedes over a distance larger

A method is developed for determining the temperature of the substrate in the area of electrospark deposition. The method is employed during experiments on deposition of two types of electrodes onto steel substrates: carbon steel electrodes and hard-

The effect of electrospark spaying on the hardness, wear resistance, and phase composition of hard-alloy coatings is investigated. A coating mechanism is proposed to consider change in dynamic properties of cathode jets depending on the interelectrod

The influence exerted by electric-spark spraying on the kinetics of mass transfer and the physicomechanical properties of coatings is investigated. It is shown that electric-spark spraying is determined by the dynamic properties of the cathode jets,

A new procedure is suggested for determining the grain size composition of polydispersed powders with a microscope. It is based on dividing the whole size range into four parts. The number of grains in the field of view is determined for each part se

The number of contacts and their character of distribution among particles are one of the key characteristics of powders, and consequently study of the internal geometry of such media is receiving a great deal of attention. The authors of the compara
