VCarb

Design and predict low-pressure carburization schedules with precision and validated DANTE diffusion models.

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
