Can zinc phosphate coating lead to Liquid Metal Embrittlement above 800F?

Zinc plating has lead to LME of austenitic stainless steel and even ferritic steels above 800 F. Can a zinc phosphate coating lead to LME of steel or 4140 HSLA steel bolts? Does anybody have any case histories or articles that prove it will or will not lead to a problem with Liquid Metal Embrittlement?
