تأثير النتردة و الكربنة السائلتين على مقاومة البلى الالتصاقي لفولاذ كربوني 1020

الملخص EN

The aim of this paper is to study the effect of Nitro carburizing on adhesive wear resistance of carbon steel (1020 AISI).

Four groups of specimens were manufactured (A, B, C, D) with dimensions (D20*10 mm) according to ASTM standard .

Liquid nitriding at 550 °C for one hour was applied for group B, liquid carburizing at 950°C for one hour was applied for group C, and double process of nitriding the carburizing in the same conditions as mentioned before was applied for group D.

The hardness test, the adhesive wear resistance at different conditions (time, sliding velocity and load) and photo microstructure was checked by optical microscope, then phases was examined by the X-ray diffraction technique for all the specimens.

It is found that the adhesive wear resistance was improved by all surface heat treatment.

Nitriding and carburizing but Nitro carburizing it found that best improvement.
