Summary
Suspension plasma spraying (SPS) effectively creates wear-resistant coatings from fine titanium and chromium carbides. This advanced process yields superior performance with minimal oxidation for demanding applications.
Area of Science:
- Materials Science
- Surface Engineering
- Tribology
Background:
- Titanium- and chromium-based carbides are crucial for wear-resistant coatings.
- Suspension plasma spraying (SPS) is an emerging technique for depositing coatings from fine powders.
Discussion:
- This study explores using aqueous suspensions of fine titanium carbide (TiC) and chromium carbide (Cr3C2) with SPS.
- Characterization included surface morphology, microstructure, phase composition, and micro-hardness of the coatings.
- Wear resistance was assessed through abrasive, erosive, and sliding tests.
Key Insights:
- SPS successfully processed sub-micron and nano-sized TiC and Cr3C2 from aqueous suspensions.
- The resulting coatings exhibited excellent wear resistance across multiple test conditions.
- Minimal in situ oxidation was observed during the SPS process.
Outlook:
- SPS presents a viable and promising method for manufacturing high-performance, wear-resistant carbide coatings.
- Further research could optimize SPS parameters for enhanced coating properties and explore other carbide compositions.

19.8K
Some solids can transition directly into the gaseous state, bypassing the liquid state, via a process known as sublimation. At room temperature and standard pressure, a piece of dry ice (solid CO2) sublimes, appearing to gradually disappear without ever forming any liquid. Snow and ice sublimate at temperatures below the melting point of water, a slow process that may be accelerated by winds and the reduced atmospheric pressures at high altitudes. When solid iodine is warmed, the solid sublimes...

Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles visible to the naked eye or seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. The suspended particles in a suspension settle out after some time of mixing. The separation of particles from a suspension is...

4.4K
When a voltage is applied to a conductor, an electrical field is generated, and charges in the conductor feel the force due to the electrical field. The current density that results depends on the electrical field and the properties of the material. In some materials, including metals at a given temperature, the current density is approximately proportional to the electrical field. In these cases, the current density can be modeled as:

5.7K
When a current moves through any conductor, the conductor causes some level of difficulty for the current to flow. The measure of that difficulty is known as the resistance of the material and is represented by R. Every material has its own resistance. In the case of conductors, heat is emitted whenever a current passes through them. Resistance depends on the resistivity of the material. Resistivity is a characteristic of the material used to fabricate electrical components, whereas the...

Clathrin-coated vesicles use endocytosis to transport receptors and lysosomal hydrolases from the Golgi to the lysosome in the late secretory pathway. Clathrin-mediated endocytosis was the first described endocytic process, and Clathrin-coated vesicles remain one of the most well-studied transport vesicles. The molecular machinery that generates clathrin-coated vesicles comprises over 50 proteins that precisely coordinate vesicle formation. Cell surface receptors concentrated in indented sites...

17.4K
Membrane-enclosed structures called vesicles transport proteins and lipids across the cell. The vesicles derive their cargo from the plasma membrane, Golgi, ER, or endosome. Coated vesicles are spherical, protein-coated carriers with a 50–100 nm diameter that mediate bidirectional transport between the ER and the Golgi. The distribution of proteins between the ER and Golgi complex is dynamic and is maintained by different coated vesicles. Their formation is driven by the assembly of...
