4. Engineering Notes & Physics Specifications
High-vacuum Electron Beam Surface Texturing & Glazing (EBST) modifies the surface topography of titanium implants, CoCrMo joint replacements, and turbine thermal barrier bond coats through rapid localized melting and vapor recoil micro-dimpling.
- Kanaya-Okayama Electron Penetration Depth:
R_KO = (0.0276 · A · E_0^1.67) / (ρ · Z^0.89)in µm. High kinetic energy electrons penetrate into the subsurface, generating subsurface boiling and Marangoni surface tension convection. - Osteointegration Topography: Micro-craters with diameters between 100–200 µm and depths of 40–80 µm promote human osteoblast attachment and rapid bone ingrowth without particulate shedding.
- Electromagnetic Vector Deflection: Fast magnetic deflection coils steer the electron beam in discrete point matrices with deflection frequencies exceeding 50–100 kHz. Prepress CAD/CAM files specify exact X-Y deflection coordinates and micro-dwell maps.
