  [Problems] To provide a lubricating coating agent for plastic working, containing a non-black solid lubricating material, and a metal material coated with the agent, which enable highly difficult forging that has been conventionally difficult to practically apply to anything except lubricating coating films containing a black solid lubricant typified by molybdenum disulfide [Means for solving] The problems can be achieved by means of a lubricating coating agent for plastic working, which is characterized by containing, at 5 mass% or more in terms of solid content ratio in a coating film, a calcium sulfate hydrate with a particular scale-like crystal shape among calcium sulfate hydrates deposited by reacting a sulfuric acid or a sulfate with a calcium compound in water, and a metal material coated with the agent.

  问题 提供一种含有非黑色固体润滑材料的塑料加工用润滑涂层剂，以及涂有该涂层剂的金属材料，该涂层剂可实现高难度锻造，而传统上，除了含有以二硫化钼为典型的黑色固体润滑剂的润滑涂层膜外，其他任何材料都难以实际应用该涂层剂。 [解决方法］ 这些问题可以通过一种用于塑料加工的润滑涂层剂来解决，该涂层剂的特点是在涂膜中含有固体含量比为 5 质量％或更高的硫酸钙水合物，该硫酸钙水合物是通过硫酸或硫酸盐与钙化合物在水中反应而沉积的硫酸钙水合物中具有特殊鳞片状晶体形状的水合物，以及涂有该涂层剂的金属材料。
