in this study, hydroxyapatite was coated on titanium substrates by plasma spraying process. a well-known porous and lamellar microstructure was found in the lateral and outer surface of coating. the phase composition was studied by xrd and the morphological and the microstructural aspects were investigated by scanning electron and optical microscopy. the hardness of coatings and substrates was ...

Cold-spraying technology is a solid-state, powder-based coating deposition and additive manufacturing (AM) technology, which utilises high-pressure gas stream to accelerate micron-sized particles through de-Laval nozzle for supersonic speed impact on substrates generate dense, high-quality deposits [...]

In tunneling and mining construction work, heavy and large manipulators are used to spray liquid concrete on the walls. These manipulators are usually operated manually with simple control units allowing to control all actuators independently. In cooperation between industry and university, we have developed a novel automatic and human-oriented control system for such a manipulator. The new con...

A component, which has a perfect combination of different materials (including homogeneous materials and different types of heterogeneous materials) in its different portions for a specific application, is considered as the component made of a multiphase perfect material. Based on the requirements for fabricating different types of heterogeneous materials, a hybrid manufacturing process with la...

The directions of research in the development process plasma spraying material are substantiated. theoretical basis for improving technology spraying.
