Abstract
Method for the in-situ deposition of a coating onto internal surfaces and matrix substrates of a body which defines one or more cavities. The single cavity, or the respective cavities packed with suitable substrates are provided with a predetermined amount of a solid reacting component to produce a suitable coating. The cavity is furnished with a liquid component which contacts the solid component, thereby forming a desired liquid coating reaction mixture. The latter is brought into contact with the cavity walls as well as with materials contained within the cavity, to achieve the desired coating of walls and matrix material.
Claims11
Method for depositing a coating layer of material onto interior surfaces of a body which defines an internal cavity having a gas pervious matrix substrate substantially occupying said cavity, the latter having at least one opening, which method includes the steps of:
- initially inserting into said internal cavity a charge comprising a solid reaction component which, when mixed with a sufficient amount of a liquid component, will form a liquid coating solution having a desired molar concentration,
- closing said at least one cavity to form a vented, liquid holding chamber within the cavity,
- introducing into said liquid holding cavity said sufficient amount of liquid component to contact said reaction component thereby to form the coating composition having the desired molar concentration,
- and maintaining said coating composition within said cavity for a sufficient period of time to deposit a coating layer on surfaces within the cavity.
