Cavitation Erosion and Corrosion of Pearlitic Gray Cast Iron in Non-Standardized Cavitation Conditions

Abstract

A results of test of erosion and corrosion resistance of pearlitic gray cast iron (grade EN GJ 400) are showed. The NaCl solutions and of ethylene glycol solutions were used as the test environment. Examination were performed at varying cavitation load, in the range 2,8 ÷ 20 W/cm2.

Factors Influencing Cavitation Erosion of NiCrSiB Hardfacings Deposited by Oxy-Acetylene Powder Welding on Grey Cast Iron

“…SEM observations confirm that erosion is initiated by the removal of the graphite phase (Fig. 6a) which follows observations of Chmiel et al and Kim et al [52,53]. This opens access for cavitation action to aggressively penetrate the metallic matrix.…”

Cavitation erosion and sliding wear resistance of HVOF coatings

“…5) allows to observe different wear mechanisms for each of the tested materials. Steel 304 shows cavitation erosion plot typical for metal alloys recorded in the literature [17,22,23]. However, the process of cavitation erosion of HVOF coatings began without a clear incubation period of cavitation erosion (characteristic for metal alloys).…”

Effect of Atmospheric Plasma Sprayed TiO2-10% NiAl Cermet Coating Thickness on Cavitation Erosion, Sliding and Abrasive Wear Resistance

“…Cermet TiO 2 -10 wt% NiAl coatings present lower resistance to cavitation than bulk metal alloys (C45 or PA2). While reading the cavitation curves of metal alloys, the incubation period of cavitation erosion and non-constant cavitation erosion rate are usually evident [25,26]. Thus the main difference in the cavitation erosion process of the ceramic-based coatings and metal alloys consists of the evident incubation stage of cavitation erosion identified for the reference PA2 and C45 samples and the negligible incubation period of cavitation erosion visible for the sprayed coatings (see Fig.…”
