Abstract

Proveer un aparato de evaluación de características de superficie y un método de evaluación de características de superficie que evalúan el esfuerzo residual en un material de acero sometido a un tratamiento de modificación de superficie al considerar la distribución del mismo en la dirección de profundidad. El aparato de evaluación de características de superficie incluye un oscilador, un detector y un instrumento de medición. El material de acero es colocado para empalmarse contra o cerca de una bobina en el detector. El oscilador aplica una corriente alterna a la bobina y el cálculo se efectúa en base a una señal que indica una característica eléctrica de la bobina. El esfuerzo residual en el material de acero se evalúa al efectuar esta operación mientras sucesivamente cambia la frecuencia de la corriente alterna. La bobina es configurada para tener una frecuencia auto-resonante más alta que la frecuencia de operación.
