- metal ions in particular silver ions, germicidal
- microorganisms on surfaces are an undesirable effect in many ways. Microorganisms may e.g. lead to spoilage of food, form unwanted biofilms and pose a hygiene risk. To curb these troublesome by-products, attempts are being made to provide surfaces that are easier to clean, as well as to develop surfaces that actively promote the growth and / or colonization of microorganisms, e.g. counteract by releasing silver ions that cause the death of the
- the antimicrobial agents are modified by various factors (e.g.
- Matrix composition can not develop their full potential.
- the coating of large or three-dimensional, complex objects, in particular with cavities, bores and the like. is often difficult and sometimes even impossible.
- the invention is based on the object, an antimicrobial metallic material, namely steel, in particular stainless steel, titanium, titanium alloy or an intermetallic compound, in particular titanium aluminide, the use of this
- Material to provide material produced by the material and a method for producing such a material, wherein the material should be manufactured and usable on an industrial and not merely purely scientific scale and to avoid the disadvantages of the known coatings.
- the object is achieved by a metallic material having the features of claim 1 or by a use of a material having the features of claim 4, by an article having the features of claim 5 and a method of manufacture having the features of claim 6 or 8.
- a metallic material according to the invention which is steel,
- Compound, in particular titanium aluminide additionally contains, in addition to the customary substances according to the invention, additionally fractions of at least one metal from the group consisting of silver, copper and zinc. Metals of this group are known for their antimicrobial properties.
- the metallic material contains a proportion of antimicrobial metal of about 0.1-10% by weight, preferably about 0.5-5% by weight, based on the total weight of the material. Too low a proportion of the antimicrobial metal has a low antimicrobial effect, too high levels of the antimicrobial metal undesirably alter the properties of the metallic material. Especially in applications in food technology and in the forwarding and treatment of water has a proportion of about 2.5 to 3 5 wt .-% based on the
- the metallic material to which, according to the invention, a proportion of antimicrobially active metal is or will be added it may in particular be so-called V2A stainless steel (X5CrNi18-10, also under the material number 1 .4301 and the AISI no.
- the metallic material is made from a powdery precursor to which has been added portions of at least one metal of the group consisting of silver, copper and zinc in powder form. This allows uniform distribution and incorporation of the antimicrobial material in a variety of materials that are otherwise difficult to mix with elements such as silver, such as certain steels.
- the invention also allows the machining of an object produced from the metallic material according to the invention, without thereby impairing the antimicrobial properties of the object. While in coated surfaces, a machining just leads to the removal of the coating, surfaces of objects made of inventive material, such as the blade of a knife, subsequently machined, for example, be ground without the antimicrobial properties get lost. It is also easily possible to introduce cavities and depressions into components produced from the material according to the invention, for example by drilling or milling, these cavities and depressions then readily having the desired antimicrobial properties.
- a method for producing an antimicrobial material according to the invention provides that in order to achieve the most uniform distribution of the antimicrobial metal in the material, the antimicrobial metal is added as a powder to a melt of the material to be antimicrobially adjusted.
- the powder may be a so-called nanopowder with very small particles.
- a uniform distribution is also achieved in which a melt of the material to be antimicrobially adjusted, the antimicrobial metal is added as a block, which then melts in the melt.
- the process is carried out under vacuum or in a modified atmosphere (e.g., a noble gas atmosphere), e.g. an undesirable
- Oxidation of the antimicrobial metal or a so-called spitting can be avoided.
- the invention also makes it possible to use a large number of objects, in particular medical devices, medical implants, articles for the pharmaceutical,
- Ticket vending machines, keyboards and the like Using the material according to the invention advantageously produce with known manufacturing and manufacturing processes, said objects then have an antimicrobial properties without additional coatings.
