الجواب وباللہ التوفیق

It is makruh for a wife to call her husband by his name.It is better to address him by his surname.For example, if their son's name is Abdullah, Abu Abdullah is a better way to address her husband, or some other polite and respectful words may be used, such as “Sayyidi, etc. 

In Fatawa Hindiah:

 یکرہ ان یدعو الرجل اباہ والمرأۃ زوجھا باسمہ کذا فی السراجیۃ (الفتاویٰ الھندیہ : الباب الثانی والعشرون فی تسمیۃ الاولا دو کناھم)

فقط واللہ اعلم بالصواب
