Should I capitalize the suffix -like in a title if it is hyphenated?

For example:

Diamond-Like Carbon Coating or Diamond-like Carbon Coating

Metal-Like Compounds or Metal-like Compounds

Which is correct?

    I wouldn't. A capital after a hyphen is not customary, except in the case of a double-barrelled personal name that is hyphenated.

  • No, no caps there.

  • This was asked on English Language and Usage and there's no firm rule (unless you have a style guide that says otherwise): often capitalizing looks better, but it depends how significant the second part is.

Precisely because 'like' is a hyphenated suffix, it should not be capitalized in a title.
