Abstract
The invention discloses a stainless steel product with an antibacterial coating and a manufacturing method for the stainless steel product, and relates to a stainless steel product with an antibacterial function and a manufacturing method for the stainless steel product. The surface of the stainless steel product is provided with the antibacterial coating; and the antibacterial coating is a titanium copper physical vaporous deposition (PVD) coating. The manufacturing method comprises the following steps of: placing the stainless steel product into a vacuum multi-arc ion plating machine; vacuumizing the machine body; heating a furnace to about 180 to 220 DEG C; electrifying; injecting argon; and reacting in the machine for 25 to 35 minutes by adopting an arc discharge method and a titanium copper alloy target to form a titanium copper PVD film on the stainless steel product. By the stainless steel product with the antibacterial coating and the manufacturing method for the stainless steel product, the problem that bacteria grow on the surface of the conventional stainless steel product is solved.
Description
Technical field
The present invention relates to have the Stainless Steel Products and the method for manufacture of antibacterial.
Background technology
Along with improving constantly of standard of living, Stainless Steel Products begins to get into human consumer's daily life.But people are using Stainless Steel Products, and especially with Stainless Steel Products during as food utensil, surface of stainless steel product can breed bacteria, the big limitations of this performance deficiency the range of application of Stainless Steel Products.
Summary of the invention
The technical problem that (one) will solve
The present invention provides a kind of Stainless Steel Products and method of manufacture that antibiotic coating is arranged, and solves the problem of existing surface of stainless steel product meeting breed bacteria.
(2) technical scheme
For addressing the above problem, the present invention adopts following technical scheme:
A kind of Stainless Steel Products that antibiotic coating is arranged: said surface of stainless steel product has antimicrobial coating, and said antimicrobial coating is a titanium copper PVD coating.
The present invention also provides a kind of method of manufacture that the Stainless Steel Products of antibiotic coating is arranged: Stainless Steel Products is placed in the vacuum arc deposition film machine, in the plated film body, vacuumize earlier and the stove that raises in temperature to 180-220 ℃; Switch on again, inject argon gas, adopt the method and the CTB alloy target of arc discharge, make interior generation of coating equipment react, reacted 25-35 minute, on Stainless Steel Products, form titanium copper PVD rete.
Preferably, the mass content of said CTB alloy target is: the titanium mass content is 0.1-20%, and copper mass content is 0.1-20%.
Preferably, the mass content of said CTB alloy target is: the titanium mass content is 1-15%, and copper mass content is 1-15%.
The present invention can produce the Stainless Steel Products of PVD coating, and these goods are on Stainless Steel Products, to increase PVD coating, make stainless steel have the antimicrobial effect.This product detects through the international certification authority of anti-biotic material inspection center of Physical Chemistry Technology Inst., Chinese Academy of Sciences and SGS, and staphylococcus aureus and colibacillary antibiotic and fungistatic effect are reached more than 99%.
Embodiment
With illustrated embodiments the present invention is done detailed explanation below.
A kind of Stainless Steel Products that antibiotic coating is arranged: surface of stainless steel product has antimicrobial coating, and antimicrobial coating is a titanium copper PVD coating.
A kind of method of manufacture that the Stainless Steel Products of antibiotic coating is arranged: Stainless Steel Products is placed in the vacuum arc deposition film machine, in body, vacuumize earlier and the stove that raises in temperature to 180-220 ℃; Switch on again, inject argon gas, adopt the method and the CTB alloy target of arc discharge, make interior generation of machine react, reacted 25-35 minute, on Stainless Steel Products, form titanium copper PVD rete.
Preferably, the mass content of said CTB alloy target is: the titanium mass content is 0.1-20%, and copper mass content is 0.1-20%.More preferably, the mass content of said CTB alloy target is: the titanium mass content is 1-15%, and copper mass content is 1-15%.
In one embodiment, the mass content of said CTB alloy target is: the titanium mass content is 10%, and copper mass content is 10%; The hardness of CTB alloy target is 1, and the hardness of CTB alloy target is 39.
PVD (Physical Vapor Deposition) refers to utilize physical process to realize substance transfer, and atom or molecule are transferred to the process on the substrate surface by the source.Its effect be can be some have specific characteristics can (intensity height, wear resistance, thermal diffusivity, rotproofness etc.) particulate be sprayed on the lower parent of performance, make parent have better properties.PVD basic skills: vacuum-evaporation, sputter, ion plating (hallow cathode deposition, HCD, hot cathode ion plating, arc ion plating, activated reactive evaporation, RF ion plating, direct-current discharge ion plating).
PVD is meant under vacuum condition; Adopt the arc-discharge technique of low voltage, big electric current; Utilize geseous discharge to make target evaporation and make to be evaporated material and ionization all takes place gas, utilize the booster action of electric field, make to be evaporated material and reaction product is deposited on the workpiece.
What the present invention adopted is the PVD technology of coating: enhancement type magnetic control cathode arc: the cathode arc technology is under vacuum condition, with high electric current the target ionization is become ionic condition through low voltage, thereby accomplishes the deposition of thin-film material.Enhancement type magnetic control cathode arc utilizes the acting in conjunction of EM field, and the electric arc of target material surface is controlled effectively, makes the ionization level of material higher, and film performance is excellent more.
Can find out that by above embodiment the embodiment of the invention makes stainless steel have the antimicrobial effect through on Stainless Steel Products, increasing PVD coating.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from know-why of the present invention; Can also make some improvement and replacement, these improvement and replacement also should be regarded as protection scope of the present invention.
