Abstract
The invention discloses a treatment technology for an inner cavity surface of a cylinder cover. The treatment technology comprises processes as follows: cleaning the inner cavity surface of the cylinder cover to remove oil and dust; preheating the inner cavity surface of the cylinder cover to 70-90 DEG C in a far-infrared heating manner; performing spraying: spraying paint onto the inner cavity surface of the cylinder cover, wherein the thickness of the coating is in a range of 60-90 mu m; performing drying: continuously keeping the temperature of the inner cavity surface of the cylinder cover in a range of 70-90 DEG C and continuously drying the coating for 5-10 min in the far-infrared heating manner; performing sintering: performing high-temperature sintering on the coating of the inner cavity surface of the cylinder cover in a laser scanning heating manner at the temperature of 190-200 DEG C for 20-25 min to form a corrosion-resistant high-temperature-resistant ceramic film layer on an inner cavity of the cylinder cover. The treatment technology has the advantages that the coating is high-temperature-resistant and corrosion-resistant and has a catalytic combustion effect, so that the combustion efficiency of an engine is improved.
Description
Technical field
The present invention relates to belong to field of metal surface treatment, specifically refer to a kind of surface of internal cavity treatment process of cylinder cover.
Background technology
Cylinder head be one of important large parts in automobile engine, in the manufacturing and designing of engine, occupy an important position, its complicated internal structure, harsh applying working condition, make its reliability become the technological difficulties in engine design.
Existing cylinder cover is all generally to adopt cast iron or aluminium to make.Because present oil quality is difficult to unified, can be doped with corrosive impurities such as urea in some slop oils, when these compositions burn in engine, the surface of internal cavity of meeting countercylinder lid causes corrosion, and the carbon granules that petrol and diesel oil burn incompletely is produced is more prone to the long-pending surface of internal cavity that is overlying on cylinder cover by the corrosion on these surfaces, cause the efficiency of combustion of engine to decline.
Summary of the invention
The object of the invention is the shortcoming and defect existing in order to overcome prior art, and a kind of inner chamber high-temperature corrosion-resistance that can improve cylinder cover is provided, adhere to thereby reduce carbon granules, keep the surface of internal cavity treatment process of the cylinder cover of the efficiency of combustion of engine.
For achieving the above object, technical scheme of the present invention is
(1) surface of internal cavity of countercylinder lid carries out cleaning, oil removing dedusting;
(2) surface of internal cavity of cylinder cover is preheating to 70-90 DEG C in Far-infrared Heating mode;
(3) spraying, is sprayed on sprayed coating on the surface of internal cavity of cylinder cover, the thickness 60-90 μ m of its sprayed coating, and the component of this sprayed coating is, in mass fraction:
Organosilicon modified crylic acid resin 35-65%
Octyl group phosphoric acid acyloxy titanate esters 1.5-3%
Nano-calcium carbonate 0.5-5%
Diamond dust 0.3-10.3%
Cyclohexanone 10-13%
Pyrophyllite powder 2.5-5.5%
Phosphatization yttrium 0.5-10%
Zirconium English powder 0.03-0.15%
Titanium oxide powder 5.2-25.0%;
(4) dry, in Far-infrared Heating mode, the temperature that continues the surface of internal cavity that keeps cylinder cover is 70-90 DEG C, continues dry 5-10 minute;
(5) sintering, utilizes the sprayed coating of the surface of internal cavity of laser scanning mode of heating countercylinder lid to carry out high temperature sintering, and sintering temperature is controlled at 190-200 DEG C, and sintering time is 20-25 minute, is formed on anticorrosive refractory ceramics rete at the inner chamber of cylinder cover.
Advantage of the present invention is that advantage of the present invention is:
(1) the anticorrosive refractory ceramics rete that the present invention forms at the surface of internal cavity of cylinder cover, corrosion resistance, resistance to elevated temperatures are good, long service life, and the surface of internal cavity of this rete and cylinder cover has formed fine and closely woven brilliant phosphatization, between rete and the surface of internal cavity of cylinder cover, adhesion is strong, and while having ensured applied at elevated temperature, the surface of internal cavity of rete and cylinder cover combines closely.
(2) the titanium oxide powder 5.2-25.0% in coating of the present invention remaines in anticorrosive refractory ceramics rete after sintering, and still can keep the physical property of titanium oxide powder, and this titanium oxide has catalytic effect, can improve the efficiency of combustion of engine.
Detailed description of the invention is described further the present invention below.
