Both ECM and EJM are anodic dissolution processes based on the electrolysis work of Faraday and are capable of material manipulation at an atomic level. Both processes enable material removal without affecting a components surface integrity and physical properties such as hardness and toughness, so do not affect the machinability.
However, EJM differs significantly from ECM in that EJM is capable of selective material removal without the need for masking due to hydraulic phenomenon. The electrolyte is also delivered as a jet in an unsubmerged manner unlike ECM which is a submerged process. This means that EJM can deliver far higher mass transport rates due to the electrolyte flow at the point of machining in comparison to ECM. Also, the impinging jet size and cooling effect of the high electrolyte flow, means much higher current density values are achievable, whilst maintaining an electrochemical removal mechanism and as such achieves up to 100% machining efficiencies.
TextureJet has developed significant proprietary innovations in hardware, software, green chemistry and application developments, such as Stat®, that enable this technology to realise its commercial potential.
