For efficient industrial applications, the amount of binder material, used in conventional processes for manufacturing zeolite shapes, need to be minimized in order to avoid undesired reactions. The manufacturing and characterization of mechanically stable compact binderless zeolite shapes with Faujasite and Linde Type A structure such as honeycombs or multi-channel tubes are described. Due to the high zeolite content and huge space filling, these shapes can increase the efficiency of conventional dynamic adsorption, catalytic or filtration processes

Nowadays, wire-arc spraying of chromium steel has gained an important market share for corrosion and wear protection applications. However, detailed studies are the basis for further process optimization. In order to optimize the process parameters and to evaluate the effects of the spray parameters DoE-based experiments had been carried out with high-speed camera shoots. In this article, the effects of spray current, voltage, and atomizing gas pressure on the particle jet properties, mean particle velocity and mean particle temperature and plume width on X46Cr13 wire are presented using an online process monitoring device. Moreover, the properties of the coatings concerning the morphology, composition and phase formation were subject of the investigations using SEM, EDX, and XRD-analysis. These deep investigations allow a defined verification of the influence of process parameters on spray plume and coating properties and are the basis for further process optimization.
