(54) Žlarovo nanesený povlek na oceli na báze hliník, zlnok, titan(54) Glaze coating on steel based on aluminum, grain, titanium
Vynález ea týká žiarových z Hat lnových povlakov xxa báze Al-Zn-Ti nanesenýoh na οοοί’οvom materiál!. Tieto povlaky eú vysoko korozně a tepelne odolná, májá dobrá tvárniteEnosť a přilnavost’ a eú vhodná ako náhrada žiarove pozinkovaných a pohliníkovanýoh pleohov.The present invention relates to heat-resistant hat liner xx and Al-Zn-Ti based coatings coated on a material. These coatings are highly corrosion-resistant and heat-resistant, have good formability and adhesion, and are suitable as a substitute for hot-dip galvanized and aluminized baldness.
V sáčasnosti ea vo svete už vyrábajú ooelové pleohy so žiarovýml zliatlnovými povlakmi Al-Zn-Si v SendzimiroveJ kontinuálněj linke. Křemík v tomto zllatinovom povlaku má inhibičný účlnok tj. zabraňuje, resp. spomaluje nařastaniu medzivrstvy vo formě intermetaliokýoh zláčenln medzi základným ooel’ovým materiálem a vlastným povlakem Al-Zn. Nevýhodou tohto žiarováho povlaku na báze Al-Zn-Sl je jeho náohylnoeť ku koráznemu odlupovaniu, tj. postupnému odlupovaniu povlaku od medzivrstvy v sline aeresívnyoh atmosférických koróznyoh prostrediaoh. Ďalžou nevýhodou tohto povlaku pri určitých aplikáclaoh je kopírovanie vytvořeného kvetu na povrohu povlaku, podobné ako zinkového kvetu pri žiarovom zinkovom povlaku, pri nanážaní nátěrových hmdt alebo fólií z plastických hmdt v kontinuálnyoh linkáoh.At the present time, and in the world, they already produce ooel puddles with Al-Zn-Si refractory alloys in Sendzimir's continuous line. The silicon in this filamentous coating has an inhibitory effect, i.e. it prevents or prevents the formation of silicon. it slows the build-up of the interlayer in the form of intermetallic paints between the base material and the actual Al-Zn coating. A disadvantage of this Al-Zn-S1-based hot-dip coating is its susceptibility to corrosive peeling, i.e., gradual peeling of the coating from the interlayer in the sinter of an aggressive atmospheric corrosive environment. A further disadvantage of this coating in certain applications is the copying of the formed flower on the surface of the coating, similar to that of a hot-dip galvanized coating, by applying coating compositions or plastic films in a continuous line.
Uvedená nevýhody rieSi žlarovo nanesený zliatlnový povlak nanesený na ooel*ovom materiál! na báze Al-Zn-Ti, ktorý pozostáva z 15-90 % hliníka, 0,01 až 1,5 # titánu a zbytok tvoří zlnok. Povlak mdže obsahovat’ ečte áalšiu legujúeu přísadu křemík v množstva 0,5 až 11The aforementioned drawbacks are solved by a glazed cast aluminum coating applied to the oel * material! based on Al-Zn-Ti, consisting of 15-90% aluminum, 0.01 to 1.5 # titanium and the remainder being zinc. The coating may contain an additional alloying additive of silicon in an amount of 0.5 to 11
Titán přítomný v zliatlne pri nanážaní žiarováho povlaku plní dvojaká funkoiu, ako Inhibitor rastu medzivrstvy, skládájáoej sa z intermetaliokýoh zláčenln, a ako očkovadlo,The titanium present in the galvanically applied coating has a dual function as an interlayer growth inhibitor, consisting of intermetallic compounds, and as an inoculant,

That is, in the case of the application of this coating for the manufacture of lacquered bald, it is not necessary to roll the bald before painting to remove the flowers.
Mimo titánu je možná súčasne ako legujúou přísadu přidat’ křemík v množstve 0,5 až $>t čím sa eSte zesilní inhibičný účlnok titánu a vzniknutá medzivrstva je eSte tenSla a rovnoměrnějSia.

The simultaneous addition of Ti and Si alloys is particularly advantageous in the application of an alloy coating as a flux in a massive steel construction, where there is the greatest danger of forming a coarser interlayer and a coarse-grained coating structure.

Early noise was not found in Al-Zn-Ti coatings, reep. Al-Zn-Ti-Si observed corrosion peeling, wherein the corrosion products of the sticks were more evenly distributed over the surface.
