以ZnCl_2-FeCl_2、ZnSO_4-Ti（SO_4）_2、Zn（NO_3）_2-Fe（NO_3）_3等混合金属氯化物、硫酸盐和硝酸盐的水溶液为原料，合成了Zn-Fe和Zn-Ti合金人工锈，并对其进行了表征。不同的阴离子和金属离子的类型，形成不同的组成和形态的锈颗粒。在ZnCl 2-FeCl 2体系中生成片状碱式氯化锌（硅钠锰矿），在硫酸盐体系中生成片状碱式硫酸锌。这些片状或片状颗粒和Zn-Ti体系中产生的纳米颗粒预计分别通过择优取向和致密堆积形成致密的锈层，并有助于Zn合金的高耐腐蚀性。
The artificial rusts of Zn–Fe and Zn–Ti alloys were synthesized from aqueous solutions of mixed metal chloride, sulphate, and nitrate such as ZnCl2–FeCl2, ZnSO4–Ti(SO4)2, Zn(NO3)2–Fe(NO3)3, and so forth, and were characterized by a variety of techniques. Rust particles with different compositions and morphology were formed, strongly depending on the types of anions and metal ions. Sheet particles of basic zinc chloride (simonkolleite) were generated in the ZnCl2–FeCl2system and the plate particles of basic zinc sulphate were formed in sulphate systems. These sheet or plate particles and the nanoparticles produced in Zn–Ti systems are expected to form compact rust layers by preferred orientation and dense packing, respectively, and contribute to a high corrosion resistance of Zn alloys.
