Advanced Low Pressure Carburizing (LPC) Simulation

VCarb enables engineers to design and predict low-pressure carburizing (LPC) schedules using the DANTE material database and diffusion models. Users can generate Boost/Diffuse sequences, evaluate carbon profiles, and develop schedules tailored to specific case depth and surface carbon targets.

Accurate LPC Analysis & Material Definition

VCarb Capabilities:

  • DANTE transformation kinetics
  • Diffusion and carbide morphology models
  • Carbon-in-solution and alloy-dependent saturation limits
  • Supports both prediction and design workflows.

 

Comprehensive Process Definition

    Prediction

  • Enter low pressure carburizing (LPC) schedule: step time, temperature, and partial pressure
  • Generate carbon and final hardness profiles
    Process Design
  • Specify carburizing temperature, gas type/pressure, target ECD, carbon at ECD, and surface carbon
  • VCarb outputs an optimized Boost/Diffuse schedule

Flexible Geometry & Control Settings

VCarb can:

  • Design and predict boost diffuse schedules for both curved and flat geometries
  • Calculate gas consumption and gas flow rate based on load surface area

Controls include:

  • Units for temperature, time, dimensions, pressure, and flow rate
  • Gas Type Factor for carrier gas mixtures
  • Carburizing Efficiency Factor for deposition rate
  • User-defined or database-defined carbon saturation limit

Boost/Diffuse Schedule Generation

Design complete LPC Boost/Diffuse cycles to achieve:

  • Specified case depth
  • Controlled surface carbon levels
  • Predictable carbon gradients throughout the part

Carbon Profile & Hardness Outputs

VCarb provides detailed results:

  • Carbon concentration vs. depth
  • Final hardness predictions
  • Carbide formation and dissolution during each boost/diffuse step
