MHC Alloy Picture Inquiry & Feedback

MHC alloy (Molybdenum Hafnium Carbon Alloy) is molybdenum-based dispersion-strengthened high-temperature structural material designed for high-energy electron beam evaporation and vacuum coating environments. During electron beam evaporation, materials are subjected to localized high-temperature melting and intense radiative heating. Evaporation sources and supporting structures must withstand high heat flux, repeated thermal shock, and metal vapor erosion, requiring high melting-point stability, low vapor pressure, erosion resistance, and excellent dimensional stability.

1. Advantages of CTIA's MHC Alloy in Electron Beam Evaporation
(1) Excellent High-Temperature Structural Stability: Maintains shape stability under localized high-energy electron beam heating.
(2) Outstanding Erosion Resistance: HfC dispersion phases improve resistance to metal vapor erosion, extending evaporation source service life.
(3) Low Vapor Pressure: Reduces contamination and impurity incorporation in high-vacuum coating processes.
(4) Strong Thermal Shock Resistance: Withstands rapid heating and cooling cycles, minimizing cracking risk.
(5) Stable Thermal Conductivity: Promotes uniform temperature distribution in evaporation sources and improves coating stability.

2. Applications of CTIA's MHC Alloy in Electron Beam Evaporation
(1) Evaporation Source Crucible Holders, Rotary Discs, and Fixtures: Used to carry evaporation materials and maintain stable geometry and precise dynamic balance under high-temperature conditions.
(2) Electron Gun Shields and Thermal Shields: Block scattered electron beams and thermal radiation, protecting chamber walls and precision mechanical components.
(3) Auxiliary Heating Systems and Thermal Field Uniformity Components: Provide heating and heat conduction to achieve uniform thermal distribution and improve coating consistency.
