Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1.Structure and drafting rules for standardization documents" Drafting. This document replaces GB/T 6383-2009 "Vibration Cavitation Test Method". Compared with GB/T 6383-2009, except for the structural adjustment and compilation In addition to logical changes, the main technical changes are as follows. a) Added the temperature control requirements for vibration cavitation test equipment (see 4.1.8); b) Added the rotating disk cavitation test device and jet cavitation test device and their technical requirements (see 4.2 and 4.3); c) Added test specimen processing accuracy requirements (see 5.1); d) Added the specifications, dimensions and requirements for rotating disk cavitation test specimens and jet cavitation test specimens (see 5.2 and 5.3); e) The temperature requirements in the test conditions have been changed (see 6.1.2, Chapter 6 of the.2009 edition); f) Added optional test condition parameters (see 6.2); g) The requirement to conduct a simulated vibration test before the test has been deleted (see 7.2 of the.2009 edition); h) Added test time requirements (see 7.6); i) Added parameter processing methods such as maximum cavitation rate and nominal incubation time (see 8.4).

This document was first issued in 1986, revised for the first time in.2009, and this is the second revision. Cavitation test method

1 Scope

This document specifies the test equipment, specimen preparation, test conditions, test procedures, data processing and test report for cavitation test. This document is applicable to material cavitation tests using test devices such as vibration cavitation, rotating disk cavitation and jet cavitation, which are used to evaluate the performance of metal materials. The damage caused by cavitation in fluid media and its cavitation resistance can be used as a reference for other materials that are subjected to cavitation caused by liquid impact.

2 Normative references

The contents of the following documents constitute the essential clauses of this document through normative references in this document. For referenced documents without a date, only the version corresponding to that date applies to this document; for referenced documents without a date, the latest version (including all amendments) applies to This document.

3 Terms and definitions

The terms and definitions defined in GB/T 10123 and the following apply to this document. 3.1 Cavitation erosion Damage process caused by the combined action of corrosion and cavitation. 3.2 The amount of material loss caused by continuous cavitation per unit time and per unit area. 3.3 The total amount of material surface loss during the test time during the cavitation process. 3.4 The relationship curve between cumulative cavitation and cumulative test time. 3.5 Relationship curve between instantaneous cavitation rate and test time. 3.6 Incubation time The initial segment of the cavitation rate versus test time curve. Note. The cavitation rate at this stage is zero or can be ignored compared with the subsequent cavitation rate. 3.7 The maximum instantaneous cavitation rate during the cavitation process. ......
