Surface Integrity in Hybrid Machining Processes

The cryogenic machining of Inconel 718 results in a thicker compressive zone beneath the surface (extending the compressive zone from 40^m to 70^m) [45]. A finer micro-structure is obtained and there is less plastic deformation on the machined surface (1-2^m thickness compared to 5-10^m in dry and/or conventional MQL machining).

2020/3/25Cryogenic Fluid Management (CFM) is a key technology to enable exploration. Whether nuclear thermal propulsion or liquid oxygen/liquid methane is chosen by Human Exploration and Operation Mission Directorate (HEOMD) as the main in-space propulsion element to transport humans, CFM will be required to store propellant for up to five years in various orbital environments.

A study on the corrosion and electrochemical properties of

The corrosion properties and passive film behaviour of wrought (WR) and electron beam melted (EBM) Ti-6Al-4V (Titanium Grade 5 or TG5) were compared in simulated physiological solution. Microstructural characterization was performed using field-emission scanning electron microscopy (FE-SEM) and X-ray diffraction (XRD) to correlate the microstructural characteristics to corrosion resistance

Thermo

During machining of Ti6Al4V the mainly thermal wear mechanisms are effected beneficial by the improved cooling of the high-pressure lubricoolant supply and cryogenic cooling. Compared to that, during machining of Inconel 718 the much more mechanical wear mechanisms are amplified by the concentration of cutting forces onto the cutting edge during machining with high-pressure lubricoolant
