Summary of the invention
Object of the present invention is exactly the critical component cylinder sleeve poor reliability that will solve high-power diesel engine, the problem that life-span is low, a kind of super abrasive nano ceramics alloy coat high power engine cylinder sleeve and manufacture method thereof are provided, utilize the failure mechanism of cylinder sleeve and piston relative movement, adopt advanced technologies and the manufacture method of cold spraying and thermal response, at the nano ceramic composite coating of inner surface of cylinder liner fabricated in situ metallurgy combination, extend cylinder sleeve working life and utilization efficiency, hardness is higher, toughness is better, durable wear; Solve the intensity stiffness issue that cold spraying coating combines, stress is little, indeformable in high temperature, can not produce de-porcelain.
Technological scheme of the present invention is achieved in that a kind of super abrasive nano ceramics alloy coat high power engine cylinder sleeve, comprise high power engine cylinder sleeve, be characterized in: described high power engine cylinder sleeve adopts nano ceramics alloy coat cylinder sleeve, make wear resisting cylinder jacket by 45 steel or nodular cast iron through processing process, inboard wall of cylinder liner matrix covers cold painting one deck nano ceramics alloy coat, and the thickness of nano ceramics alloy coat is 0.1-0.3mm; Nano ceramics alloy coat composition is superfine graphite powder, aluminium powder, nano-silica powder, straight iron powder, water, boric acid, phosphoric acid, lauryl sodium sulfate.
A manufacture method for super abrasive nano ceramics alloy coat high power engine cylinder sleeve, is characterized in: its manufacturing step is as follows:
1) cleaning: first centrifugal casting system 45 steel cylinder sleeve or nodular cast iron cylinder sleeve, then 45 steel cylinder sleeves or nodular cast iron cylinder sleeve steel base are put into ultrasound deoil, sandblasting removing inboard wall of cylinder liner surface oxide layer, makes surface clean;
2) cold painting nano ceramics alloy coat: after cylinder sleeve steel base cleaning, at surperficial cold spraying nano ceramics composite alloy, nano ceramics composite alloy composition is superfine graphite powder, aluminium powder, nano-silica powder, straight iron powder, water, boric acid, phosphoric acid, lauryl sodium sulfate; 0.1-0.3mm is thick in inwall cold painting; After spray after doing, transient heating, to 2000 DEG C-2700 DEG C, forms thermal response composite nano-ceramic alloy coat; Nano ceramics alloyed powder composition is:
The present invention with ceramet coating, can increase substantially and extend the working life of the motors such as boats and ships, train, automobile at wear-resistant engine cylinder liner surface, improves antiseptic property; The high hard flawless of the present invention, cylinder sleeve thermal conductance speed in high temperature is fast, and indeformable not de-porcelain, reduces cost, decrease the scrappage of product; Surface roughness is Gao Keda 0.09um more.
Embodiment
Super abrasive nano ceramics alloy coat cylinder sleeve of the present invention makes wear resisting cylinder jacket, cold painting one deck nano ceramics alloy coat, the thickness 0.1-0.3mm of nano ceramics alloy coat by 45 steel or nodular cast iron through processing process.
The manufacturing step of super abrasive nano ceramics alloy coat of the present invention is as follows:
1, cylinder sleeve 45 steel or nodular cast iron centrifugal casting matrix: 45 steel or nodular cast iron matrix are put into ultrasound and deoils, sandblasting removing inboard wall of cylinder liner surface oxide layer, makes surface clean;
2, cold painting nano ceramics alloy coat: adopt cold spraying, in spraying process, first sand blast inboard wall of cylinder liner surface; Cold spraying nano ceramics alloy coat again: air pressure controls: from dry after 0.4-0.7mpa, cold spraying thickness 0.1-0.3mm, spray, transient heating is to 2000-2700 degree.Wherein, nano ceramics alloyed powder composition is: superfine graphite powder, aluminium powder, nano-silica powder, straight iron powder, water, boric acid, phosphoric acid, lauryl sodium sulfate, and composition is:
