Effect of the carburizing paste concentration on the case depth of carburized low carbon steel / Muhammad Hafizuddin Jumadin

Pack carburizing is a theme—chemical treatment used to increase the mechanical properties of steels. It is an easy, low cost and safe compare to gas and fluid carburizing. However, this process requires additional temperature and soaking time because of limitation of carbon diffusion. Research condu...
