Method.
Background technique
In cannon military service situation, ablation is always an important factor for influencing barrel life, especially in high-energy propellant
When, ablation is more significant to the corrosion function of gun barrel.In shooting course, thorax bears gunpowder combustion in a short time in barrel
The high temperature of gas, is washed away and is corroded with chemical attack at high pressure, while also by the extruding of bearing band and abrasion, operating condition is very severe.It is passing through
After crossing a certain number of shootings, high temperature powder gases generate ablation damage to thorax in barrel, with the exacerbation of interior thorax degree of injury,
Directly affect the war skill index such as fire accuracy, initial velocity.
In Canon launching, the instantaneous temperature of gunpowder detonation is up to 2500~3500K, barrel inner wall temperature can 5~
Reach 1270K in 50ms, the powder gas under high temperature has extremely strong chemical erosion to barrel.Gun propellant, typically by

Warm high pressure and the operating condition washed away can tentatively reach the evaluation of ablative to material fire-resistance medicine or special gunpowder ablation property.
But closed or half close guarantor's explosion test requires to be ignited by gunpowder, has certain risk, and test sample needs
It is processed into ring specimen, for some materials, process is more difficult.And the experiment side of other common ablation simulations
Method all mainly examines or check the ablation effect of heat including oxy-acetylene flame method, laser stationary point method, arc erosion method, it is difficult to simulate
The chemical erosion of artillery lumen acts on.Therefore, it invents the more rapidly and efficiently safer method of one kind and carrys out simulation material fire-resistance
