Abstract.
The advantage of manufacturing complex part geometries with varied materials is the key in these technologies.
This is mainly due to the low maintenance cost and wide use of available materials.
The raw material in the form of strands is then fed through the extruder in the FDM machine.

Introduction The high-wear-resistant wires have great potentials during many mechanical applications, therefore, it’s proposed in this article that whether the chemical vapor deposition (CVD) technology, especially the most practical hot filament CVD (HFCVD) technology in the industrial field, can be applied for depositing high-quality diamond films on the wires made of certain appropriate materials, with the purpose of developing a novel type of high-wear-resistant wires.
The most commonly-used basis material for conventional mechanical wires, the steel has proved to be unsuitable as the substrate of HFCVD diamond films, because (1) the Fe element can cause severe graphitization of the diamond; (2) the steel has very high carbon solubility and the Fe3C has high instability in the austenite phase; (3) the high substrate temperature required in diamond films growth will have a strong impact on the properties of the steel; (4) the difference between thermal expansion coefficients of the steel and the diamond is very large [1, 2].
Among the suitable substrate materials, the tungsten is a feasible choice as the substrate material of the diamond coated wire, on account of its favorable toughness and low thermal expansion coefficient close to the diamond.
Consequently, further studies focusing on the issue if the deterioration of the tensile and bending strengths will affect the application of the coated wire are required in following researches, and it’s also essential to further explore preferred substrate materials for fabricating diamond coated wires.
