- Abstract
In this work tungsten carbide coatings have been deposited onto AISI/SAE 1018 steels by using thermal spray process and by setting three types of flames viz. reducing, neutral and oxidizing. Results indicated that percent of porosity is lower in specimens made upon reducing type of flame and the microstructure is composed of semimolten and un-molten particles, non-lamellar structure, and with presence of oxide stringers. Hardness measurements upon reducing condition resulted above 1000Hv due to presence of hard particles of WC and W2C. Moreover, the sliding wear resistance upon reducing condition was acceptable according to the analysis made under different testing conditions of loading and sliding time. Finally, it is concluded that tungsten carbide particles and the relatively high hardness value has strong influence on the sliding wear resistance in spite of the observed porosity.
