Actually defuze appears to be the Arabic spelling of defuse. You are correct though that it should not be diffuse.
defuze. Verb. (third-person singular simple present defuzes, present participle defuzing, simple past and past participle defuzed) Archaic spelling of defuse.
defuze. Verb. (third-person singular simple present defuzes, present participle defuzing, simple past and past participle defuzed) Archaic spelling of defuse.
