Innovation Utilization of Nitridation Method in Improving Hardness and Corrosion Resistance of Blacksmiths Crafts

Abstract

Hardness and corrosion resistance are properties that must be possessed by blacksmiths. One of the main problems of this small blacksmith industry is the process of finisihings handicrafts, weak mechanical properties and poor corrosion resistance making it difficult to compete for a wider market nationally and internationally. The purpose and aim of this research is to assist the blacksmith craft industry in increasing hardness and corrosion resistance so that the results of these crafts can compete at the national and international levels. The Plasma Nitriding method and the field nitriding scale by spraying Nitrogen into the results of blacksmith crafts heated under recrystallization temperatures. On the scale of nitriding the field is by spraying nitrogen as a cooling medium on the results of the blacksmith craft that has been preheated at temperatures of ± 723 to 900 ºC. The hardness level of the blacksmith craft test specimens carried out by the nitriding process increased hardness (HRC) by 17.5% and with corrosion resistance increased by 35% from the row material.
