The material became more viscous and the bonding of the successive layers was improved.
All 4 specimens proved similar complex viscosity, a small difference was recorded for the material heated by the normal resistive heater (green line), which showed a more viscous material.
Based on the DSC thermal analysis, the material suffered the following modifications: · A decreasing with 5-8% of the material stiffness was recorded when the IR lamp was introduced.

Cathodic arc evaporated CrAlSiN coatings with multi-cycle depositions Yen-Shuo Changa, Wei-Yu Hoa, Po-Yi Tsoua, Cheng-Liang Linb a Department of Materials Science and Engineering, MingDao University, Taiwan b Department of Electro-Optical and Energy Engineering, MingDao University, Taiwan a:weiyuho@mdu.edu.tw Keywords: Cathodic arc evaporation, CrAlSiN coating, erosion Abstract: CrAlSiN film possesses superior hardness, good thermal and chemical stability due to its multi-component constituents and unique structure.
To further explore the reproducibility and scale-up thickness of CrAlSiN coatings, the multi-cycle deposition of CrAlSiN coatings by cathodic arc evaporation was conducted in this study in order to evaluate the effect of coating thickness on the properties of CrAlSiN coated materials.
However, the hardness of the silica powders is much higher than that of the droplets which are mainly metallic target material.

The circulation economy guides the economic activity through both of the ecology rules and movements of the materials circulation in ecosystem.
Introduction As a part of ecological economy, circular economy guides the economic activity of human being through both of the ecology rules and movements of the materials circulation in ecosystem.
They first strongly challenged the traditional concepts of unlimited excess growth[1] [2] in 1968 , in his important article, “Economics as a Science”, Kenneth Boulding propose the concept of “Ecological economy”.

The results show that compared with the traditional peak aging process, two gradually cooling three-step aging process is to improve materials tensile strength, plastic and impact toughness in different degrees.
Meanwhile corrosion resistance of materials has improved significantly.
Introduction Al-Zn-Mg-Cu series alloys are one of the most important structural materials and used extensively in aviation and spaceflight because of their high strength-to-weight-ratio, attractive specific stiffness, durability, low cost, machinability and easy formability[1].
