Thermal spray engine coatings: Solve common problems with engines
- Details
The development of engine coatings
There are an estimated 2 billion combustion engines being used worldwide. Whilst many manufacturers are turning their attention to the advancement of electric vehicle technology, there are some manufacturers who understand that the internal combustion engine will remain in service for a long time to come.
Applications of tungsten carbide coatings in the aerospace industry
- Details
What are tungsten carbide coatings?
Tungsten carbide is a chemical compound of tungsten and carbon, which appears as a light grey powder in its most basic form. With an extremely high melting point, tungsten carbide is often used to create thermal spray coatings.
Creating biocompatible coatings for medical devices
- Details
Biocompatible coatings are designed to be compatible with living systems. This means that when a coating is in contact with a living system, it should not trigger a reaction. In the medical industry, it has become increasingly popular to use biocompatible coatings on implants and instruments, to avoid patients having an adverse reaction to these devices.
Advances in thermal barrier coatings for gas turbine engine applications
- Details
The first jet engine is believed to have been developed in the 1930s, during the second world war. Having gone through countless iterations, this invention was regarded as one of the biggest breakthroughs in aviation history. Since then, there have been major advancements in the aviation industry, including the development of the ramjet and scramjet. However, despite the advancements that have been made to jet engines in recent years, there are still a number of problems that occur.
HVOF Thermal Spray: What it is and why it’s replacing Hard Chromium Coating Electroplating
- Details
High Velocity Oxygen Fuel (HVOF) is a thermal spray coating which is used to improve the strength and durability of a component’s surface. The process involves fuel and oxygen continually igniting and combusting in a combustion chamber, in order to produce a hot gas which is then injected with a powder feed stock. The hot gas and powder are released as a jet stream and directed towards a component, producing a powder coating which forms a hard-wearing surface.
