Description
Technical field
The present invention relates to preprocess methods before a kind of polyamide resin resin-based composite thermal spraying on surface protective coating, belong to
Field of surface engineering technique.
Background technology
Polyamide resin resin-based composite relies on low specific strength height, friction coefficient, endurance and good corrosion resistance, hinders energy of making an uproar
The strong advantage of power is contained outside aero-engine and is obtained on the components such as casing, fancase, compressor blade, inlet casing extensively
Using.Not only the loss of weight requirement of aviation operational aircraft of new generation had been met, but also has considerably reduced cost.
However, the current normal working temperature of polyamide resin resin-based composite makes inside at 350 DEG C hereinafter, working as and tempering occurring
When temperature sharp rises to 600 DEG C even 800 DEG C, multiple material ablation scaling loss will occur in a short time and lead to not continue to take
Labour, therefore, the anti-yaw damper protection of polyamide resin resin-based composite is current problem in the urgent need to address.
Mainly the research including heatproof resin material is modified and in current material table for the approach of raising ablation resistance at present
Face prepares anti-yaw damper protective coating.（1）Pass through the existing polyamide of modification, Development of Novel resin, such as graphite/polyamide;Development
Heat resistant polyamide novel flame-retardant system, such as bromine system flame retardant systems（Firemaster@CP-44HF、Saytex@HP-3010、
SaFRon5251-DF, F-3100, halogen-free flameproof system（Red phosphorus, melamine salt, Exolit OP）；In the selection of reinforcing material
Aspect has:Carbon fiber, glass fibre, K2Ti6O13 whiskers and mica enhancing etc..But external state-of-the-art polyamide at present
The temperature tolerance of based composites also only has 380 DEG C, to be promoted to 800 DEG C or more, difficulty is big to be anticipated that.（2）Using heat
Spraying process prepares heat-resisting anti-yaw damper or resistance to high temperature oxidation protective coating on resin material surface.
Anti-yaw damper or high temperature coatings material are mostly ceramic material or ceramic-metal composite, and hot-spraying technique is with it
The advantages such as power is high, technique is flexible, easy to operate, coating layer thickness is controllable, have very big in terms of preparing ceramic base protective coating
Advantage.Thus composite material surface spraying prepares ablation resistance of the anti-yaw damper coating than improving polymer matrix composites itself merely
Can have better operability, also be more in line with circular economy and the strategy and policy policy of sustainable development.However it adopts at present
Coating is directly carried out on resin base matrix surface to prepare in the presence of very big problem, be mainly manifested in hot-spraying technique：
（1）Matrix have thermal sensitivity, overheat is easy to happen in thermal spray process, because internal stress is excessive deform and divide
Layer failure.
（2）Thermal spraying molten state spraying particle is not easy to merge bonding with matrix, it is difficult to deposit, binding force is very weak（Mainly by
In polymer matrix composites with protective coating metal and ceramic material matching in physical and chemical performances such as coefficient of thermal expansion
There are larger differences, and there are difficulty for the bond vitrified between composite material and barrier material）.
The above problem keeps preparing for multiple material surface erosion-resistant protective coating seriously hampered.It is applied to advanced aviation at present
Polyamide compoiste material on engine components is directed to the anti-burning of polyamide compoiste material there is an urgent need for promoting its Burning corrosion resistance energy
It loses protective coating and studies rare report, the combination promoted while for how to realize coating deposition between coating and basis material is strong
Degree also lacks effective implementation.
In addition, have technical solution to choose the material that fusing point is low, caking property is good first prepares prime coat before prepared by carry out face layer,
To enhance the binding force of coating.But the anchoring strength of coating realized at present is in 5MPa or so, the actual requirement with application
（10MPa or more）It compares, there is also prodigious gaps.
