Abstract

The resistance of deposited layers to cavitation erosion and abrasive wear was evaluated for the steels AISI 321 (known as 06X19H9T manufactured according to the Russian standard GOST 18143-72) and Fe-Cr-Ti-Al (two materials namely Ural AS-3 and PPM-6). The Gas Tungsten Arc Welding (GTAW or TIG) process was utilized to deposit these welding material wires onto a medium carbon steel substrate AISI 1040. Cavitation test was conducted by using ultrasonic vibratory method to induce the erosion. In addition, a three-body abrasion test was used to evaluate the resistance of the studied materials to abrasive wear. The material loss criterion and wear rate of each material as a function to testing time were evaluated and discussed. The cavitation and abrasive wear tests have shown similar results regarding the PPM-6 steel. Among the tested material, PPM-6 exhibited the better resistance to cavitation and abrasion. The 06X19H9T stainless steel exhibited a higher resistance to cavitation comparing with the Ural AS-3. With respect to the abrasive wear, Ural AS-3 was to some degree better than the 06X19H9T in resistance to abrasion.

Highlights

  • Wear, in general, is common to occur in machinery components that serve many industrial applications in the fields of oil, mining and mineral processing

  • There is a slight difference in mass loss between Ural AS-3 and the 06X19H9T so that Ural AS-3 is better than the 06X19H9T by 10% approximately

  • A little difference can be recognized between Ural AS-3 and 06X19H9T at the beginning of test, while a distinct difference can be seen comparing with the PPM-6

Summary

Introduction

In general, is common to occur in machinery components that serve many industrial applications in the fields of oil, mining and mineral processing. Abrasive wear is one of the most important types of wear in which the damage involves a progressive loss of material due to the presence of hard particles rolling between two sliding surfaces. Abrasion wear resistance is very important, ; the development of materials and technologies to protect the surfaces of components and increase the wear resistance are necessary for the performance and lifetime of machinery components [1,2,3,4,5,6]. Many laboratory testing methods can be considered to evaluate the wear resistance. The three-body abrasion test is the most common. The rotating rubber wheel, test specimen, and the solid hard particles are the basic elements in the test which is considered as a low-stress method [7]
