Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, below in conjunction with the accompanying drawings and it is embodied as
The present invention will be further described for example.It should be appreciated that specific embodiment described herein is only in order to explain the present invention, and without
In the restriction present invention.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creative work premise
Lower obtained every other embodiment, belongs to the scope of protection of the invention.
The metal alloy coating of the present invention, by weight percentage, key component is：
Silver-colored 30%-45%, titanium 15%-28%, germanium 4%-12%, cobalt 1%-5%, magnesium 2%-9%, copper 2%-10% and ferrum
5%-18%.Silver plays the role of anti-inflammation and sterilization, but hardness is not high, only the half of the hardness of ferrum.Titanium, the hardness of cobalt are the 2 of ferrum
More than times, the mechanical strength of coating can be strengthened.Additionally, titanium can stimulate phagocyte, the enhanced work(of body immunity is made
Effect is confirmed, titanium vessel can make the food color of preservation lasting as silverware by medical science.Cobalt has stimulation hemopoietic
Function.Germanium has unusual effect at body-care, anticancer, aspect for cancer.Magnesium has ferment function, can aid in the absorption of calcium and potassium,
Prevent heart disease, diabetes, nocturia, also have the effect for reducing cholesterol.
As minor metallic element contained by areal variation human body is also not quite similar, reported according to threpsology, can close on basis
Suitably increase and decrease other metal ratio beneficial to human body in gold to add with micro form, adapt to different geographical crowd, to micro gold
Category element and the alloy of nonmetalloid demand, for example, add the phosphorus of 0.05%-2% and the selenium of 0.5-3%.Phosphorus is helped to maintain
The balance of body soda acid, assist metabolism and energy production, and selenium have outstanding to anticancer function；Molybdenum is a kind of group of enzyme
Part, this enzyme can be catalyzed purine and change into uric acid, and Microamounts of Mo is the constituent of ommochrome, favourable to eyes；Manganese participates in many
Enzymic catalytic reaction, is that all living things be unable to do without.
When the base material 12 of coating is for smart ferrum or cast iron, can suitably reduce the content of ferrum in coating, and add other to people
The beneficial metallic element of body, such as manganese and molybdenum, its addition is should ensure that meeting the relevant regulations such as state food safety criterion,
Addition is respectively preferably 0.1-1%.
The coating of coating can carry out electric arc spraying using B alloy wire, it is also possible to by alloy make powder using flame or wait from
Sub- technology is sprayed.By taking electric arc spraying as an example, referring to Fig. 1, it is first according to metal alloy composition ratio and carries out proportioning make conjunction
Gold.The alloy for obtaining is drawn into the B alloy wire 2 of diameter 1.6mm-3mm, preferably 1.6mm, B alloy wire 2 press state food level standard and
European Union's ROSH standard.B alloy wire 2 is admitted to ignition tip 6 by wire feeding disc 3 and wire pushing roller 4, the atomizing space gas blowout through overcompression
Penetrate, form spraying particle stream 10 and deposit formation metal alloy coating 11 on the base substrate 12.Wherein, running voltage to rationally be controlled
And electric current, this plays vital effect to forming dense coating.Running voltage is 30-36V, and operating current is 200-
300A, it is 150-200mm that atomization air pressure is 0.8MPa, spray distance；Finally give painting of the thickness for more than 0.5-2mm
Layer.
