Spark testing to measure carbon content in carbon steels based on fractal box counting

•Spark testing to measure carbon content based on fractal box counting is proposed.•Box counting analysis is used to calculate the fractal dimension of spark picture.•An exponential function is employed to describe carbon content and fractal dimension. Spark testing is an effective and inexpensive w...
