Abstract

Un objetivo es proporcionar una lámina de acero eléctrico que tiene un recubrimiento aislante, la lámina de acero eléctrico tiene excelente resistencia al desprendimiento del recubrimiento que se puede exhibir durante un proceso de estampación, de modo que se impide la pegadura del recubrimiento a una matriz. Una lámina de acero eléctrico que tiene un recubrimiento aislante incluye una lámina de acero eléctrico y un recubrimiento aislante dispuesto sobre por lo menos una de las superficies de la lámina de acero eléctrico. El recubrimiento aislante incluye un material compuesto que contiene P y Al y que tiene una relación de aspecto de 1 a 10, el material compuesto tiene un diámetro de partícula de 10 nm 10 a 1000 nm, y el recubrimiento aislante tiene un espesor de 500 nm a 2000 nm.
