Most AM components require a post-processing step to refine mechanical properties or reduce stress. In many cases, heat treatment may be applied to achieve the final desired level of functionality. For instance, it may be necessary to eliminate internal porosity or voids within the printed part. Alternatively, a greater level of material hardness may be required. Or cleaning may be needed to achieve the surface finish demanded by the target application.
We provide a broad range of gases, gas mixtures, supply systems and cleaning solutions to ensure optimum post-treatment and surface cleaning outcomes. See below for a brief outline of our offering.
Gas atmospheres play an important role in enabling de-lubrication of sintered parts and avoiding decarburization. We have developed a dedicated technology to control the sintering process and improve the mechanical strength of sintered parts. Complementing our sintering gases and gas mixtures, our SINTERFLEX® offering gives you precise control over your gas atmospheres.
Various industrial coating technologies are used in additive manufacturing to improve component properties such as resistance to wear-and-tear and corrosion. They do this by adding a layer with the desired composition or properties. We can help you select the right thermal coating process, using the right gas compositions and the right supply solution for your thermal spraying needs.
Hot isostatic pressing (HIP)
The final heat treatment step, HIP is used to eliminate internal porosity and voids within cast metal materials and components. This is a particularly important step to extend the reliability and service life of high-performance components, such as those used in aerospace and aviation. We can ensure you have the right inert atmosphere for your HIP process.
