"镀银餐具" can be translated into English as "silver-plated tableware" or "silver-plated cutlery".
"Silver-plated" indicates that the items are coated with a layer of silver.
"Tableware" is a general term for eating and serving utensils, while "cutlery" specifically refers to knives, forks, and spoons. Depending on the context, either term can be appropriate. If referring to a broader set of items including plates, bowls, etc., "tableware" is more suitable.
