Metal-coated seat retention groove

A valve comprising:

• a valve body defining a body bore having a bore axis, the valve body further defining a channel coannular with the body bore, the channel comprising an outer edge defining an annular seat retention groove, wherein the annular seat retention groove is coannular with the body bore of the valve body;
• a corrosion-resistant metal barrier over the annular seat retention groove, the corrosion-resistant metal barrier defining a first edge and a second edge, each of the first edge and second edge coannular with the body bore;
• and
• an epoxy coating over the first and the second edges.

A method of manufacturing a valve with a corrosion-resistant barrier, the method comprising:

• obtaining a valve body defining a body bore having a bore axis, the valve body further defining a channel coannular with the body bore, the channel comprising an outer edge defining a seat retention groove;
• and
• thermal spraying a corrosion-resistant barrier over the seat retention groove, wherein the corrosion-resistant barrier is metal, wherein thermal spraying comprises heating a material forming the corrosion-resistant barrier, and spraying a plurality of particles resulting from heating the material;
• and
• applying epoxy to the valve body after thermal spraying the corrosion-resistant barrier.
