Abstract:
This paper analyzes, by comparison, the cavitation erosion resistance of the samples treated through softening annealing at 710 ± 10 °C with the purpose of partial spheroidization of pearlite and decomposition of free cementite traces from the microstructure, respectively the samples treated through normalizing at 860 ± 10 °C with the purpose of the pearlite proportion increasing and the cavitation erosion resistance improving. Cavitation tests were conducted on a vibrating device with piezo-ceramic crystals, following standard rules ASTM G32-2010.The microstructure characterization of the heat treated and eroded by cavitation was made by optic microscopy, and scan electronic microscopy.The obtained results show an improvement of cavitation erosion resistance after the application of the heat treatment for normalizing as a follow-up of the structure finishing and growing of the pearlite proportion in the base matrix..

Abstract:
Some surface treatments that apply to the hydraulic equipment components, which operated at high hydrodynamic loads, in which appear the phenomenon of erosion by cavitation, shall be listed and laser nitriding. Before that operation, the steel was undergone thermal annealing treatments for improving machinability cutting, followed by martensitic quenching and a tempering to high temperature. [..]

Abstract:
Martensitic heat-resistant steel P92 belongs to very progressive group of 9-12% Cr steels modified with vanadium and niobium, with controlled boron and nitrogen content. P92 has got excellent creep properties and it is used very often to build the most exposed parts of supercritical units in steam power plants.The goal of this article is to compare the real welded joints with the simulated samples and to optimize the heat treatment and welding process of P92 steel.
