Hardening of surgical blades

Hardening surgical blades

Objective: Rapid heating of a steel surgical blade to 2000 °F (1093 °C) within 2 seconds to harden its edge.

Material: Stainless steel surgical blades, temperature sensing paint

Temperature: 2000 °F (1093 °C)

Frequency: 339kHz

Equipment: Ambrell 3kW induction heating system, remote heat station containing one 1.0 microfarad capacitor..

Process: A four turn helical coil is used to harden the blades. The induction coil is designed to provide uniform heat to the entire length of the blade surface. RF power is applied to heat the entire assembly. The blade reaches the necessary temperature for hardening in 1.2 seconds.

Results:

• Does not affect core structure.
• Targeted and rapid heating.
• Repeatable process.
