Description
Technical field
The invention belongs to ship air propeller designing techniques, are related to a kind of desertification erosion wear-resistant aluminum alloy blade.
Background technique
With the continuous development of shipbuilding industry, modern ships constantly develop to economization, functionization, high speed direction, from
From the aspect of existing market, aircushion vehicle has wide development as fields such as rapid transit, emergency management and rescue, tourist recreation and military affairs
Space has the characteristics that safety, timeliness, water route are amphibious.A weight of the propeller blade as power system of hovercrafts
Component is wanted, Materials are gradually diversified, and also higher and higher to its performance requirement, aluminium alloy is due to the high, quality with intensity
Gently, the advantages that good corrosion resistance, resistance to cavitation corrosion, service life length, propulsive efficiency height and good comprehensive performance, so being ship
With the ideal material of airscrew blade.
Primary aluminum alloy vane uses metal hemming edge structure, and blade surface sprays corrosion resistant coating, in actual operation process
In, blade is washed away seriously by sandstone, and metal hemming edge fracture, corrosion resistant coating falls off, and causes blade damage serious.
Summary of the invention
The object of the present invention is to provide a kind of desertifications for marine propuision system to lose wear-resistant aluminum alloy blade.
The technical scheme is that wear-resistant aluminum alloy blade, including blade body, front edge rubber, glue are lost in a kind of desertification
Tie agent, wear-resistant coating is lost in desertification；The front edge rubber is two layers；The front edge rubber is coated on blade body edge；It is described
Blade body leading edge is bonded as one by cementing agent and first layer front edge rubber；Second layer front edge rubber passes through cementing agent and the
One layer of front edge rubber is bonded as one；Wear-resistant coating is being lost without the blade body external coating desertification at front edge rubber.
Further, the front edge rubber is symmetrically distributed in blade body leading edge two sides, and unilateral width is 50mm.
Further, the thickness of the front edge rubber is 0.5mm.
Further, desertification erosion wear-resistant coating with a thickness of 0.5mm.
Further, the cementing agent is 561-2 type cementing agent.
The beneficial effects of the present invention are: desertification erosion wear-resistant aluminum alloy blade of the present invention is using high-intensitive aviation reflectal
Manufacture uses front edge rubber clad structure to blade, and loses wear-resistant coating in blade surface brushing desertification, can be effectively
Salt fog is obstructed between the corrosion aluminium alloy vane ontology crystal, has many advantages, such as that resisting salt fog corrosion, desertification stone wash away.
Detailed description of the invention:
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is cross-sectional view of the present invention shown in Fig. 1 along line A-A；
Fig. 3 is partial enlarged view shown in Fig. 2；
Wherein, wear-resistant coating is lost in 1- blade body, 2- front edge rubber, 3- cementing agent, 4- desertification.
Specific embodiment
The following further describes the specific embodiments of the present invention with reference to the drawings.
Blade for propeller is to be able to satisfy to run in the ocean water surface and seabeach for a long time, is now coated to blade inlet edge
Abrasive rubber material need to make following place according to the impaired place's situation of the practical corrosion of previous blade and test result of blowing sand to blade
Reason:
(1) it now needs to coat blade inlet edge into the front edge rubber 2 that two layers of thickness is 0.5mm, unilateral width is 50mm.
(2) wear-resistant coating 4 is lost in the desertification that (without at leading edge cladding) brushes 0.5mm thickness on 1 surface of blade body, thus really
Protecting the blade, to achieve the effect that desertification is lost wear-resisting.Referring to Fig. 1, Fig. 2, Fig. 3.
Specific process details are as follows:
(1) blast processing is done on 1 surface of blade body, it is ensured that it is be bonded with blade body 1 securely that wear-resistant coating 4 is lost in desertification.
(2) cementing agent 3 twice will be brushed with 2 bonding plane of front edge rubber after pickling at 1 leading edge cladding of blade body, so
Front edge rubber 2 is coated in 1 leading edge of blade body by cementing agent 3 afterwards, then vacuumizes pressurization admittedly by certain time
Change ensures that 2 covering material of front edge rubber is be bonded with blade body 1 securely.The cementing agent is 561-2 type cementing agent.
(3) after the blade after coating leading edge is cleaned up with acetone solvent, then with soft rubber scraper plate brushing specific thicknesses
Desertification lose wear-resistant coating 4, it is necessary to guarantee coating brushing orientation consistency (not brushing at leading edge cladding), the blade after brushing
It is put into the solidification for carrying out certain time certain temperature in curing oven, is taken out after cooling, desertification can be obtained and lose wear-resisting aluminium conjunction
Gold leaf piece.
(4) desertification erosion wear-resistant aluminum alloy blade is put into blowing machine, with 90 mesh sand grains, 0.25MP pressure carries out blade
Blast test after being kept for 45 minutes, checks that blade surface desertification erosion 4 thickness abrasion loss of wear-resistant coating is not more than 0.05mm.
Claims (4)
1. wear-resistant aluminum alloy blade is lost in a kind of desertification, it is characterized in that: the blade include blade body, front edge rubber, cementing agent,
