The article in accordance with the invention is a corrosion and erosion resistant article having good release characteristics which includes a metal body having a first surface thereon and a base coat adhering to the first surface. The base coat comprises at least one layer of inorganic particulate material bonded to the first surface. A second coat adheres to the base coat. The second coat comprising a cured coating of solid particulate lubricant in a phosphate/chromate metal ion solution. The invention also includes a corrosion and erosion resistant coating having good release characteristics which includes a base coat, the base coat comprising at least one layer of inorganic particulate material bonded to the first surface; and a second coat adhering to the base coat. The second coat comprises a cured coating of solid particulate lubricant in a phosphate/chromate metal ion solution. The invention also include the method of applying a corrosion and erosion resistant coating having good release characteristics which indicate providing a metal body having a first surface thereon and applying a base coat to the first surface where the base coat comprises at least one layer of inorganic particulate material bonded to the first surface. The next step comprises partially curing the base coat, and applying a second coat that adheres to the base coat, the second coat comprises a cured coating of solid particulate lubricant in a phosphate/chromate metal ion solution. In some cases a third coat is applied.
