In this work, the influence of preliminary vibration stress on the stabilisation of structure and properties of the surface layer of steel compounds with electric-spark coatings is presented.
Laws of the formation of properties eutectic gas-plasma coating on an iron-base containing interstitial phases depending on a degree of nonequilibrium conditions are established. It is shown that, after high-temperature diffusion annealing, eutectic coatings work on deterioration in a pair with the couched steel better than up to annealing. A conclusion is drawn on self-organising structure and properties...
The quality and the quantity assessment of the structure of the AlSi13Cu2 alloy matrix composites reinforced with carbon fibre in the amount of 5, 10, or 15 vol. percent has been presented. Due to the poor wettability of carbon fibre by molten AlSi alloy and the low castability of the examined composites, the Ni-covered fibre with 0.25 [mikro]m thick Ni layer has been used and the pressure casting...
