Diamond coating

Weber Technologies GmbH uses a hot wire CVD process for the deposition of diamond coatings on various base materials. CVD stands for Chemical Vapor Deposition. In this case, the process gases introduced into the coating chamber are decomposed by means of heated filaments under vacuum and the carbon atoms are deposited on the substrate surface, so that a crystalline diamond layer is growing through the entire deposition process.

Diamond coating process

The entire coating technology, including chemical pretreatment come from a single source.
Our range of services include micro- and nanocrystalline coating, as well as gradient structured diamond coating in thickness layers ranging from 3 to 20 μm.

Properties and applications

WT DIA coatings are used for machining in CFRP, CFRP/Al stack material, Ceramics, Graphite and Al-alloy materials. Combined with high-performance tungsten carbide cutting tools designed specifically for these applications, our diamond coatings provide the best results.

Fibre Material

Carbon fibre reinforced polymer is a composite material in which carbon fibres are embedded in a plastic matrix (such as epoxy resin). The matrix serves to connect the fibres and to fill the gaps between them. CFRP is used particularly where the increased costs are accepted for a low mass and simultaneously high rigidity. Examples are bicycle frames, rowing boats and accessories and compressed gas containers. Here, the mechanical properties of the cured composite benefit above all from the tensile strength and stiffness of the carbon fibres.

The fibre-reinforced materials, which are expensive to produce, are used above all in areas where their advantages (usually weight savings) result in at least a correspondingly high cost-saving potential, such as in aerospace and, in future, also in vehicle construction.

Graphite

Graphite is a modification of carbon and crystallizes hexagonal. At room temperature and normal pressure graphite is the thermodynamically stable form of carbon. It is obtained by pyrolysis and graphitised by means of pressing processes and subsequent temperature treatments. Graphite is mainly used as graphite electrode and in mould making.

Ceramic

(ZrO2) Ceramics The ceramic material, zirconium dioxide, is used in dental materials for dental prostheses and is gaining year on year market share. The blank dental prostheses are first made from zirconium dioxide powder to so-called green bodies by a uniaxial or isostatic dry pressing process. After shaping the green bodies, heat treatment, i.e. de-binding and presintering, follows. In this way, important properties of the zirconium dioxide green bodies such as strength, hardness and shrinkage factors are adjusted. The production of crowns or bridge frameworks are carried out using diamond-coated carbide cutters. Here, microcrystalline diamond coatings show an excellent performance.

Aluminium

Aluminium-Silicon alloys (AlSi) are aluminium alloys consisting mainly of aluminium - with silicon as the most important alloying element in terms of quantity. Copper occurs in almost all technical alloys, at least as an admixture. This also improves machinability. Important areas of application are, for example, automotive parts, including cylinder heads, crankcases, engine blocks and pistons.
