The beneficial effect that the present invention reaches:
(1) cost is low
Replaced relatively costly Zn with a large amount of Al, cost is significantly descended, save Zn20 ~ 50%, the usage quantity of the noble metal element in additive of using relatively less, can also use and receive that aluminium, zinc and other non-ferrous metal are useless, old, the foreign material material, improve cycle efficiency and recycle value, reduce costs; Utilize in addition surface reaction buffering element, violent combination reaction between Al and Fe matrix in the time of can effectively being suppressed at immersion plating reduces or stops generation " lensing Fe
2Al
5", strengthen " lamelliform Fe
2Al
5" generting machanism, set up the reaction mechanism of Fe-Al-Zn uniform gradient, thereby improve quality of coating, attenuate thickness of coating, save material, reduce costs.
(2) performance is good
Utilize the polarization alterant element to the atomic polarization reducing effect of solvent element al and Al+Zn, effectively adjust the structure of atomic size and short-range order under microstate, make melt even structure on macroscopic view, reduce surface tension, and improve the affinity of melt and plating piece matrix, reach and improve coating and matrix tack; Utilize simultaneously the relative stability of rare precious metal and easily diffusion, easily be enriched in surperficial characteristics, coating material and plating piece are produced and keep beautiful surface attractive in appearance; Rare your element of minute quantity can produce unusual effect; Utilize Li to generate strengthening phase, farthest improve the intensity of coating; Actual strength can surpass steel matrix; Utilize the effect of solvent passivation Elements C o, can be in the acid-and base-resisting of solvent surface enrichment one deck, salt and hot environment atomospheric corrosion, have that the fixing protection of grid under microcosmic and mobility cover damage surface automatically concurrently and the passivation film that plays defencive function; For preventing unwanted color occurring after the oxidation of single passivation element, can use two kinds and two or more complex element passivator; Utilize grain-refining agent, when high temperature by dissolving, diffusion and disperse, become nano level and even more tiny foreign atom cluster and stable molecular cluster, tiny " crystal seed ", gap phase and the interstitial compound that are evenly distributed in a large number are provided when the melt cooling crystallization, the grain size number of efficient refinement matrix, improve intensity, toughness, hardness, wear resistance and the high-temperature behavior of coating material, and then improved processibility and the weldability of plating piece; Utilize the comprehensive action of rare earth element additive La, have the multiple booster action of atomic polarization, alloy strengthening, grain refining, surface-beautifying, dehydrogenation and enhancing erosion resistance; The precipitation hardening agent is also the ageing strengthening agent, they are that fusing point is not high, also not high metallic element of chemically reactive, add this a small amount of dvielement, keep nearly simple substance state in alloy system, although solidify but temperature still under higher state in system, they still keep liquid, thereby make system possess the semi-solid state feature on macroscopic view, provide condition for strengthening element in acceleration alloy in the ageing strengthening process is converted into actual reinforcement attitude (precipitation hardening or precipitation-hardening); Can give simultaneously the good processing characteristics of alloy and wear resisting property; By controlling kind and the addition of precipitation hardening element, can also obtain the plating piece surface detail.
