Abstract
A kind of high-temperature corrosion-resistant coating of ferrous materials is made up of the mixture of aluminium oxide powder, alumina fiber and zinc white.With itself and water glass furnishing suspension solution, be sprayed on the surface of ferrous materials, and then the workpiece that will be sprayed is dried under 200 ℃-300 ℃ temperature, steel material surface promptly forms one deck corrosion-resistant coating, iron and steel parts with this corrosion-resistant coating, in pyritous aluminum or aluminum alloy liquation, have superior corrosion resistance, the life-span of the iron and steel parts that need work in the aluminum or aluminum alloy liquation is greatly improved.
Description
The present invention is a kind of under hot environment, and the corrosion-resistant coating material of ferrous materials in the aluminum or aluminum alloy liquation belongs to the technical field of the protection against corrosion coating of ferrous materials.
At present, in 600～1000 ℃ molten aluminium alloy, the etching problem of ferrous materials is very serious, even stainless steel also can be snapped erosion when working soon in high temperature aluminum liquid, or generates iron-aluminium frangible compounds and damages; In addition, traditional coating zinc white (ZnO) method although corrosion stability is made moderate progress, but still is difficult in the medium-term and long-term use of high temperature aluminium alloys liquation.For this reason, it is very necessary seeking a kind of more efficiently high-temperature anticorrosive coating.
Purpose of the present invention just provides a kind of under hot environment, and ferrous materials has the ferrous materials corrosion-resistant coating of good corrosion resistance in the aluminum or aluminum alloy liquation.
Corrosion-resistant coating prescription of the present invention and complete processing are as follows:
To cross the aluminium sesquioxide (Al of 320 mesh sieves
2O
3) powder is main, the percentage composition of its weight adds 7%～5% alumina fiber and 45% following zinc white (ZnO) again in 50%～95% scope, mix mix well after, with water glass (nNa
2Omsio
2) with this powder mix furnishing suspension, at room temperature, with air compressor with this liquid spray on the workpiece that cleans up, in 200～300 ℃ big stove, toasted 3～4 hours then.Take out air cooling, the surface of iron and steel parts promptly forms-50～100 μ m thick even, densification, anti-corrosion, and firm white coating.The content of zinc white is few more, and the etch resistant properties of coating is just good more.The diameter of alumina fiber is about 5 microns, and its length is 1～2 millimeter.
The invention has the advantages that this coating has superior erosion resistance, after surface of steel workpiece coated this coating, this workpiece can long term operation in the aluminum or aluminum alloy liquation and be not corroded, and has prolonged the work-ing life of this workpiece effectively, and has reduced production cost.In addition, owing in coated material, added alumina fiber, make the peeling resistance of this coating greatly improve.In coated material, also added zinc white, therefore made the cost of this coated material reduce greatly,, can also regulate the add-on of zinc white according to the job requirement of reality.So that cost and coating quality have a suitable preferred value.
Embodiment of the present invention are as follows:
With soft steel is example, at first, removes the rusty stain of workpiece surface, and cleans up, to be dried after, will cross the Al of 320 mesh sieve
2O
3Powder (85%wt) alumina fiber 5%wt and zinc white (10%wt) mix, and add an amount of water glass (account for gross weight 50%) then, and furnishing thin liquid shape in the spray gun of packing into, is opened the compressor of calming the anger.Make air pressure reach 2～4 kgfs/cm
2Between the time, open spray gun, workpiece surface is sprayed equably, and gauge control is about 60～100 μ m, then, close spray gun, workpiece moved in 300 ℃ the air furnace baking 3 hours, and took out the back air cooling, the surface of steel promptly forms a densification, anti-corrosion coating, test shows: the soft steel with this coating can life-time service in 880 ℃ molten aluminium alloy, and unlikely surface corrosion phenomenon.
In order to lower the cost of coating, generally in aluminium oxide powder and fiber, add an amount of zinc white, the add-on of zinc white is decided according to the specific requirement of workpiece, and the add-on of zinc white is low more, and its coating quality is good more, but cost is also high more; Otherwise the cost of the slightly inferior coating of coating quality then can lower many, but the add-on of zinc white generally is no more than the amount of aluminium sesquioxide.Just can realize the present invention according to the above.
Claims (4)
1, a kind of in the aluminum or aluminum alloy liquation corrosion-resistant coating of ferrous materials, the material that it is characterized in that this coating is by 50%～95% aluminium oxide powder (Al
2O
3) and 7%～5% alumina fiber add that the zinc white (ZnO) below 45% mixes.
2, the high-temperature corrosion-resistant coating of ferrous materials according to claim 1 is characterized in that its coating process is: the mixture of aluminium oxide powder, alumina fiber and zinc white is added water glass (nNa
2Omsio
2), furnishing suspension is sprayed on the surface of ferrous materials, places it in then under 200 ℃～300 ℃ the condition to toast 3～4 hours.
3, the high-temperature corrosion-resistant coating of ferrous materials according to claim 1 and 2, the thickness that it is characterized in that coating are 50～100 μ m.
4, the high-temperature corrosion-resistant coating of ferrous materials according to claim 1 and 2 is characterized in that described alumina fiber, and its diameter is about 5 microns, and its length is 1～2 millimeter.
