CemeCon's sputter technology – exceptional performance guaranteed

Unlike with the arc PVD process, with the sputter PVD process the coating material is not melted down first but transferred directly from a solid to a gaseous state. This means that no droplets (bead-shaped macroparticles on the surface of the coating) can form as a result of the process and extremely smooth coatings are achieved. In addition, the temperature ranges, within which sputter PVD coatings are produced, are considerably lower than with CVD processes. Theoretically speaking, there are no constraints on the choice of elements, unlike with the arc PVD and CVD processes. Sputter technology opens up an array of possibilities in terms of the choice and combination of coating materials.

CemeCon is the market leader in sputter technology

The CemeCon sputtering PVD process has formed the basis of high-quality coatings for over 25 years. Back in 1988, CemeCon managed to cost-effectively deposit TiAlN coatings on an industrial scale. Since then, CemeCon has developed coating materials which have made machining new materials economically viable for the first time and led to tangible performance improvements. Numerous patents on coatings, processes and technology are evidence of this.

Advantages of CemeCon PVD coatings at a glance:

• Low residual stress
• Very smooth coatings without the formation of droplets
• High level of hardness and hot hardness
• Exceptional adhesive strength
• Oxidation-resistant
• Low friction
• Deposition of thick coatings possible due to very low internal stress
• No roundings on the cutting edges, sharp edges also on thick coatings
• Cost-effective production in both small and large batches
• High flexibility in the choice of coating materials due to practically unlimited combinations of periodic-table elements for producing coatings
• Possibility of also depositing conductive and non-conductive materials on all substrata in the future
