Claim:
A mounting arrangement for mounting a turbine blade in a spray coating apparatus, comprising: a first wall having a first wall first edge and a first wall second edge where the first wall second edge is arranged opposite the first wall first edge; a second wall arranged opposite the first wall having a second wall first edge and a second wall second edge where the second wall first edge is in-line with the first wall first edge and the second wall second edge is in-line with the first wall second edge; a third wall arranged between the first and second walls spanning between first wall first edge and the second wall first edge; a fourth wall opposite the third wall arranged between the first and second walls spanning between first wall second edge and the second wall second edge; a bottom portion spanning a lower edge of the first, second, third and fourth walls to form a five-sided box-like structure; a cavity defined by an inner portion of the box-like structure having a rim arranged at an opening of the cavity that receives the turbine blade such that a root region of the turbine blade surrounded by the cavity and a blade region of the turbine blade protrudes away from the cavity opening wherein a gap is formed between the rim of the cavity opening and a portion of the blade region that adjoins the blade; a plastic shielding layer arranged between the rim of the cavity opening and the portion of the blade region that adjoins the blade root where the plastic shielding material is resistant to the spray coating; and clamping members to allow for retaining of the shielding layer to a given wall within the cavity; wherein the shielding layer includes a shielding plate arranged in the gap between the blade and the rim of the cavity opening and the shielding layer is applied such that the shielding layer projects beyond the shielding plate.
