Application and Preparation of Enteric Coating Materials

In this paper, polymethacrylate enteric coated materials based on the equal mass of methyl acrylic acid and ethyl acrylate as the main raw materials were synthesized through emulsion polymerization. Omeprazole Enteric-coated Capsules were prepared by the fluidized bed coating technology using above materials as enteric layer and in vitro enteric test was considered according to standard. The re...

Formation and Properties of Ni-Based Amorphous Metallic Coating Produced by HVAF Thermal Spraying

A highly dense Ni59Zr20Ti16Si2Sn3 partial amorphous metallic coating, about 500mm thick, was fabricated by means of HVAF (High Velocity Air Fuel) thermal spraying. Amorphous alloy powders produced by using gas atomization were used for HVAF thermal spraying to produce an amorphous metallic coating. Microstructural investigation showed that crystallization and oxidation occurred during thermal s...

Breaks in Thermal Spraying Processes

The detection of structural changes in time series from industrial processes monitoring is of great interest. We investigate the limits and possibilities of two recently developed methods, one for the off-line detection of changed volatilities [Wied et al., 2011] and one for the on-line detection of changes in the course of the time series [Borowski and Fried, 2011]. The investigation is carrie...

Hot Corrosion Behavior of Functional Graded Material Thermal Barrier Coating (RESEARCH NOTE)

In this paper a functional graded material (FGM) thermal barrier coating (TBC) is prepared using Atmospheric Plasma Spraying (APS) method. The FGM layers were deposited by varying the feeding ratio of CYSZ/NiCrAlY and conventional CYSZ on a NiCrALY-coated Inconel 738 substrates. Hot corrosion behavior, bonding strength and the related failure mechanisms of a conventional TBC and a FGM TBC are i...
