A crystalline chromium deposit having a lattice parameter of 2.8895+/&#x2212;0.0025 &#x212b;, and an article including the crystalline chromium deposit. An article including a crystalline chromium deposit, wherein the crystalline chromium deposit has a {111} preferred orientation. A process for electrodepositing a crystalline chromium deposit on a substrate, including providing an electroplating bath comprising trivalent chromium and a source of divalent sulfur, and substantially free of hexavalent chromium; immersing a substrate in the electroplating bath; and applying an electrical current to deposit a crystalline chromium deposit on the substrate, wherein the chromium deposit is crystalline as deposited.

A method and biological cleaning system are provided for cleaning substrate surfaces of oils and/or greases using a biological cleaning system which utilizes a pre-treatment bath and/or post-treatment bath as part of the cleaning system. The pre-treatment and/or post-treatment baths are compatible with the biological cleaning bath and during operation of the system, the used pre-treatment and/or post-treatment baths are recycled to the biological cleaning solution for biodegradation. A system is provided in which none of the pre-treatment, post-treatment or biological cleaning baths need expensive waste disposal. Replenishment pre-treatment and/or post-treatment baths as well as biological cleaning baths are added as needed to the biological cleaning system. Other treatment baths may be added directly to the biological cleaning bath with or without pre- or post-treatment for specific purposes such as a detergent phosphating bath used in the biological cleaning tank to provide a cleaned phosphated part.
