Abstract

The invention relates to a method for detecting trace migration components in a thermal insulation layer in a propellant bonding system used for non-destructive static analysis of aerospace polymer chemical fuels. The detection steps are: sample preparation, condition selection, map collection, and data analysis; during sample preparation, obtain the bonded test piece of the thermal insulation layer / lining layer / propellant, cut the fresh bonded surface with a blade, and make the sample to be tested; conditions When selecting, the detection object is the trace migration component of the thermal insulation layer / lining layer bonding surface, and the detection equipment is a time-of-flight secondary ion mass spectrometer; the selection conditions for spectrum collection are: primary ion source, voltage threshold, imaging method, target current value, vacuum state, acquisition time, ion mode, and calibration ion; it uses the time-of-flight secondary ion mass spectrometer to conduct qualitative determination and semi-quantitative analysis of the migration components of the adiabatic layer through spectrum acquisition and data analysis, and obtains its distribution status information. The invention also has the advantages of accurate qualitative and intuitive maps.

Description

technical field

[0001] The invention relates to a secondary ion mass spectrometry analysis method of aerospace polymer chemical fuel, in particular to a method for detecting trace migration components of a thermal insulation layer in a propellant bonding system. Background technique

[0002] In the solid propellant / liner / insulation layer bonding system, the migration components of the insulation layer are directly related to the interface bonding performance, so qualitative and quantitative detection is needed. In the prior art, it is still possible to detect the known migration components of the heat insulation layer, but there is no ready-made technology for the detection of the unknown migration components of the heat insulation layer, especially the detection of trace migration components of the heat insulation layer. Contents of the invention

[0003] The object of the present invention is to provide a detection method for the trace migration components of the thermal...
