Microstructural Characterization of Ni(Co)CrAlY Powders Designed for Thermal Spraying of Bondcoat for TBC Systems MOSKAL Grzegorz1,a 1Silesian University of Technology, Department of Materials Science, 40-019 Katowice ul.
Introduction Thermal barrier coatings are usually made up of four layers [1-4]: outer ceramic zone, bondcoat of Ni(Co)CrAlY type or diffusion layer of (Ni,Pt)Al type, growth of barrier oxide layer resulting from temperature increase and substrate material.
Experimental procedure The powders of Ni-23Co-17Cr-12.5Al-0.45Y, Co-32Ni-21Cr-8Al-0.5Y and Ni-22Cr-10Al-Y type are the basic material for analysis.

Effect of the enzymatic hydrolysis on starch properties Jing Li 1College of Material Science and Chemical Engineering,Tianjin University of Science and Technology,Tianjin ,China e-mail address: 514985570@qq.com Keywords: α-amylase; hydrolytic time;viscosity;structure ;mechanical Abstract: In this article, corn starch was modified by α-amylase with different hydrolytic time (30, 60, 90 and 120 min) and the effects of modification technology on its properties of viscosity, compound structure and mechanical were studied.
The performance of modified starch that hydrolyzed by 30 min was better than others and pinholes were generated in the surface of starch granules Introduction Starch is a cheap and abundant worldwide material, which is applied in the area of medical, agriculture and industry[1].
Plastics and fast food industries have realized that they need to begin to develop renewable sources of raw materials as petroleum supplies decline.

Joining by upset bulging can be employed for joining tubes with other structures such as sheets, plates, tubes or profiles as well as for joining different materials.
These requirements cause a clear trend towards the application of high-strength materials and multi-material designs.
Summary and outlook Joining by upset bulging gains increasingly more attention as an alternative mechanical joining method to produce hybrid components of combined different materials or high strength – low strength materials.
