Klimov V.G., Nikitin V.I., Zhatkin S.S. Restoration of height of GTE blades with high-temperature powdersolders
The process of restoration of the geometry of the turbine blade stylus TS (turbostarter) manufactured by casting of heat-resistant alloy ЖС6-К of aviation turboprop engine НК- 12МП is analyzed. A comparative analysis of two types of recovery of stylus’s geometry has been carried out: the reduction by soldering with powder solder ВПр24 in ceramic forms and laser powder cladding ВПр24 in a powder bath. The structure of reconstructed layers by means of electron microscopy with elemental analysis of transverse microsections has been explored. It is recommended to use pulsed laser powder cladding (build-up welding) for this purpose.
Key words: Laser cladding (build-up welding), self-fluxing solder, powder bath, regenerative repair, electron microscopy, elemental analysis, micro hardness, soldering.

Lyutyi R.V. Hardening of core sands with orthophosphoric acid and alumocontaining compounds of different class
Discussed are issues of developing core sands that are hardened by a fundamentally new scheme – as a result of interaction of orthophosphoric acid HPO with a number of alumocontaining materials (ACM), and contain no ready binders or scarce hardeners/ Also presented are results of making a binder at interaction of HPO with aluminum nitrate.
Key words: Aluminosilicate, aluminum nitrate, aluminum phosphate, binder, core mixture, phosphoric acid, sludge, X-ray analysis.

Korotchenko A.Y., Kutsaya A.Y., Tverskoy M.V., Khilkov D.E. On the methods of designing tier gating systems
The analysis of references showed that recommendations about the choice of values of elements of multistage feed systems are practically absent, and those which are need specification. By means of computing model operation ratios of the areas of elements of the multistage feed systems providing serial filling with a melt of a cavity of a foundry core are established.
Key words: Multistage feed system, melt flow, fiber filling, hybrid technologies.
