Abstract
The invention relates to the preparation technique of thermally spraying a nano coating on the surface of an air cylinder for an automobile engine, in particular to the air cylinder with a nano alloy coating. The nano alloy coating is arranged on the surface of a metal base body of the air cylinder, wherein the coating is formed by one or more of nanoscale ferrum, nickel, molybdenum, chromium, aluminum or other metal materials or formed by mixing one or more of nanoscale aluminum oxide, titanium oxide, silicon oxide, zirconium oxide, magnesium oxide, silicon carbide, tungsten carbide, chromium carbide or other ceramic materials into the nanoscale metal materials. The thickness of the coating is 100-1000 micrometers, and the mass ratio of the metal materials to the ceramic materials is 1: (0-1). The coating is firmly combined with an air cylinder body, has high thermal shock resistance, surface hardness and abrasion resistance, and can reduce weight of the cylinder body and the whole volume under the condition without reducing effective volume of the cylinder body. A preparation method of the coating is simple and convenient, pollution is not caused, and adverse effect on personnel and the environment is avoided.
Description
Technical field:
The present invention relates to the preparation technology of motor car engine, be specifically related to the preparation of cylinder surface hot-spraying nano coating with cylinder.
Background technique:
In order to reduce engine weight and cost, and obtain better oil consumption, the automobile engine cylinder-body material turns to lighter aluminium alloy cylinder from ironcasting gradually at present.The major defect of aluminium alloy cylinder is that wear resistance is relatively poor, and in order to improve its wear resistance, the cylinder sleeve lining that usually need make steel is as the aluminium alloy cylinder inwall, to improve its wear-resisting property.But the use of cylinder sleeve has not only increased cost, and has reduced the effective volume of cylinder body, has influenced fuel efficiency.
Summary of the invention:
The objective of the invention is to, to deficiency of the prior art, the automobile engine cylinder that provides a kind of surface to have the Nanoalloy coating utilizes its high abrasion, high tensile cylinder performance and low coefficient of friction performance, improves the purpose of motor overall performance.
Technological scheme of the present invention is following:
Cylinder with Nanoalloy coating of the present invention; Comprise the cylinder metallic matrix; It is characterized in that, on the surface of said metallic matrix, be provided with the Nanoalloy coating, this coating is made up of in nano level iron, nickel, molybdenum, chromium, aluminium or other metallic material one or more; Perhaps constitute by in nanoscale metal material, mixing in nano level aluminium oxide, titanium oxide, silica, zirconium oxide, magnesia, silicon carbide, Tungsten carbite, chromium carbide or other stupalith one or more; The thickness of said coating is the 100-1000 micron, and the mass ratio of metallic material and stupalith is 1 in the coating: (0-1).
In the cylinder with Nanoalloy coating of the present invention, described Nanoalloy coating adopts the preparation of HVAF technology; Used raw metal or ceramic raw material are nanoscale powder material.During use,, after mist projection granulating is processed the powder that particle diameter is the 40-100 micron, carry out HVAF more earlier as existing technology.
The present invention utilizes plasma spray technology for the improvement of engine cylinder-body a kind of good solution to be provided.Replace cylinder sleeve at the direct spraying of wearable coating of inboard wall of cylinder block; Because coating is thin; Under the situation of the effective volume that does not reduce cylinder body, alleviated the weight of cylinder body greatly, also reduced the overall volume of cylinder body; Therefore in actual the use, can reduce overall weight and reduce to take up room through the compact structure form.
In the Nanoalloy coating of cylinder according to the invention, metals such as the iron of use, nickel, chromium can make coating and cylinder body form firm combining, and the ceramic phase material that mixes can improve thermal shock resistance, surface hardness of coating etc. effectively.Simultaneously,, and have higher anti-ablation ability and the low coat system that self weares and teares, therefore can reduce the friction between piston ring and cylinder barrel surface, thereby reduce oil consumption because this coating has good abrasion resistance.That is to say that the present invention can further satisfy low oil consumption that alternate-engine improves constantly, low cost, in light weight, usage requirement such as the space is little.
Cylinder with Nanoalloy coating of the present invention not only can be used for petrol engine but also can be used for diesel engine, and the preparation method of its nano-structured coating is simple and convenient, and is pollution-free, can not have a negative impact to personnel and environment.
