Effect of Al2O3 nanoparticles and strontium addition on structural, mechanical and tribological properties of Zn25Al3Si alloy
(Springer Heidelberg, Heidelberg, 2018)
Nanocomposites were synthesized via compocasting using Zn25Al3Si and Zn25Al3Si0.03Sr alloys as the matrices and nanoparticles of Al2O3 (1 wt%) as the reinforcement. Structure of the nanocomposites was examined, and their ...
Selection of the optimal hard facing (HF) technology of damaged forging dies based on cooling time t8/5
(Faculty of Metallurgy, 2016)
In exploitation, the forging dies are exposed to heating up to very high temperatures, variable loads: compressive, impact and shear. In this paper, the reparatory hard facing of the damaged forging dies is considered. The ...
Determination of bond strength between the hard-faced (HF) layer and the base material (BM) of forging dies
(Faculty of Metallurgy, 2016)
This paper points out complex working conditions of forging dies, which are the most frequent causes of their damage, and proposes suitable hard-facing repair procedures. The shear strength between the hard-faced layer and ...
The Influence of Modifying Methods on the Quality of Eutectic and Hypereutectic Silumine for Diesel Engine Pistons
(International Journal of Cast Metals Research, 2013)
The results of the investigation of the influence of different modifiers (sodium, phosphorus, antimony and strontium) on the quality of AlSi12CuMgNi and AlSi18CuMgNi alloys, which are used for the production of pistons, ...
