Changes In The Structure And Properties Of Zro2 Detonation Coatings During Annealing, B. K. Rakhadilov, D. N. Kakimzhanov, G. Botabaeva, D. B. Buitkenov, N. Kantai, L. B. Bayatanova Dec 2020

Changes In The Structure And Properties Of Zro2 Detonation Coatings During Annealing, B. K. Rakhadilov, D. N. Kakimzhanov, G. Botabaeva, D. B. Buitkenov, N. Kantai, L. B. Bayatanova

Eurasian Journal of Physics and Functional Materials

The article studied the effect of annealing on the structure and properties of zirconium dioxide coatings obtained by detonation spraying. Detonation spraying was realized on a computerized detonation spray ing complex of the new generation CCDS2000. Determined that coatings made of zirconium dioxide are characterized by high adhesive strength of adherence to the substrate. Thermal annealing of coated samples was performed at temperatures of 900-1200C. It was determined that the microhardness of zir conium dioxide coatings increases by 10-25% depending on the annealing temperature after annealing. The results of nanoindentation showed that the nanohardness of the coatings after …

Obtained Of Powder Coatings By Detonation Spraying, D. B. Buitkenov, B. K. Rakhadilov, Zh. B. Sagdoldina, M. Maulet

Eurasian Journal of Physics and Functional Materials

In this work, consider the aspects of obtaining powder coatings that possessing certain working properties obtained by detonation spraying. Experimental research were carried on the effect of technological parameters of the detonation spraying process on the phase composition and properties of Ti-Si-C coatings. It is determined that when the volume of filling the detonation barrel with an explosive mixture increases to 70% in the detonation wave flow, the Ti3SiC2 powder partially decomposes into TiC consequently the high-speed shock interaction of heated to high temperatures. Installed that when filling the barrel with an explosive mixture of 50% and …


The Effect Of Detonation Spraying On The Phase Composition And Hardness Of Al2o3 Coatings, B. K. Rakhadilov, D. B. Buytkenov, D. Kakimzhanov, R. S. Kozhanova, G. S. Bektasova Jun 2020

The Effect Of Detonation Spraying On The Phase Composition And Hardness Of Al2o3 Coatings, B. K. Rakhadilov, D. B. Buytkenov, D. Kakimzhanov, R. S. Kozhanova, G. S. Bektasova

Eurasian Journal of Physics and Functional Materials

The article were studied the e ect of detonation spraying on the structure and properties of Al 2 O 3 coatings. It was determined that reducing the delay time between shots is leading to increase the hardness and elastic module of Al 2 O 3 coatings. It was found on the basis of X-ray di raction analysis that the main reason for the increasing in hardness with a decreasing in the delay time between shots is associated with increasing in the volume fraction of α -Al 2 O 3 phase. The studies of X-ray di raction presented that the highest …
