1. 16. Corrosion Behavior of HVAF-Sprayed Bi-Layer Coatings

   Författare :Esmaeil Sadeghimeresht; Nicolaie Markocsan; Per Nylén; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal spray coating; HVAF; Corrosion protection; Galvanic corrosion; Composition; Microstructure; EIS; Polarization; OCP; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

   Sammanfattning : In a variety of engineering applications, components are subjected to corrosive environment. Protective coatings are essential to improve the functional performances and/or extend the lifetime of the components. LÄS MER

3. 17. Towards more sustainable approaches for protecting surfaces against wear

   Författare :Kaveh Torkashvand; Mohit Kumar Gupta; Nuria Espallargas; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wear; HVAF spraying; WC-Based Coatings; Sustainability; Binder Chemistry; Slitage; HVAF; WC-baserade beläggningar; Hållbar produktion; Bindemedelskemi; Production Technology; Produktionsteknik;

   Sammanfattning : WC-Co coatings, with and without chromium additives, are widely used in the industry for severe tribological applications. However, concerns about cobalt supply and its environmental and health impacts have led industries to explore sustainable binder alternatives. LÄS MER

4. 18. Enhancement of the Tribological Properties of Plasma Sprayed Alumina

   Författare :Richard Westergård; Richard Warren; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap;

   Sammanfattning : Thermal spraying is the name of a large group of coating deposition techniques used to deposit thick layers for a variety of applications. The principle is to melt the material, and rapidly propel the droplets towards a substrate where they flatten and solidify. When properly used, the substrate is not significantly heated. LÄS MER

5. 19. Microstructure and oxidation behavior of High Velocity Oxy-Fuel spray deposited Ti2AlC coatings

   Författare :Marie Sonestedt; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coatings; High Velocity Oxy-Fuel HVOF ; Ti2AlC; oxidation; microstructure; SEM; TEM;

   Sammanfattning : Ti2AlC is one of the ternary carbides in the MAX phase group of materials. This group of materials have a unique combination of ceramic and metallic properties, such as machinability, high thermal conductivity, low density and oxidation resistance. LÄS MER

7. 20. Contributions to multivariate process capability indices

   Författare :Ingrid Tano; Anders Lundquist; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matematisk statistik inriktning industriell statistik; Mathematical Statistics with special emphasis on Industrial Statistic; Matematisk statistik; Matemathical Statistics; Manufacturing and materials engineering;

   Sammanfattning : The work presented in this thesis considers multivariate process capability indices (MPCIs) with focus on confidence intervals and tests for MPCIs. It also includes a case study, where multivariate statistical analysis and MPCIs are applied to data from a thermal spraying process at Volvo Aero Corporation. LÄS MER
